   <element name="introContent">
      <annotation>
         <documentation>
            The introContent element defines the body of the intro content file.  The content file is made up of pages, shared groups that can be included in multiple pages, extensions to anchor points defined in other configurations, or replacements of existing elements.

   <element name="page">
      <annotation>
         <documentation>
            &lt;p&gt;
This element is used to describe a page to be displayed. The intro can display both dynamic and static pages. Content for dynamic pages is generated from the subelements of the page, described below. The style or alt-style will be applied depending on the presentation. The styles can be further enhanced by referencing the id or class-id.
&lt;/p&gt;
&lt;p&gt;
Static pages allow for the reuse of existing HTML documents within one&apos;s introduction, and can be linked to from any static or dynamic page. Static pages are not defined in a page element, they are simply html files that can be linked to by other pages.
&lt;/p&gt;
&lt;p&gt;
The home page, whose id is specified in the presentation element of the intro config extension point, can have a url indicating that it is a static page.  If no url is specified then the home page is assumed to be dynamic.  All other pages described using the page element are dynamic. Also note that when the SWT presentation is used and a static page is to be displayed, an external brower is launched and the current page remains visible.
&lt;/p&gt;
&lt;p&gt;
The subelements used in a dynamic page are as follows: A &lt;b&gt;group&lt;/b&gt; subelement is used to group related content and apply style across the grouped content. A &lt;b&gt;link&lt;/b&gt; subelement defines a link which can be used to link to a static or dynamic page and run an intro action/command.  A link is normally defined at the page level to navigate between main pages versus links within a page. A &lt;b&gt;text&lt;/b&gt; subelement defines textual content at the page level. A &lt;b&gt;head&lt;/b&gt; subelement is only applicable for the Web based presentation and allows for additional html to be added to the HTML &lt;b&gt;head&lt;/b&gt; section. This is useful for adding java scripts or extra style sheets. An &lt;b&gt;img&lt;/b&gt; subelement defines image content for the page level. An &lt;b&gt;include&lt;/b&gt; subelement allows for reuse of any element other than a page. An &lt;b&gt;html&lt;/b&gt; subelement is only applicable for the Web based presentation and allows for the embedding or inclusion of html into the page&apos;s content. Embedding allows for a fully defined html file to be embeded within an HTML &lt;b&gt;object&lt;/b&gt; by referencing the html file. Inclusion allows for including an html snippet directly from an html file. A &lt;b&gt;title&lt;/b&gt; subelement defines the title of the page.  An &lt;b&gt;anchor&lt;/b&gt; subelement defines a point where external contributions can be made by an &amp;lt;extensionContent&amp;gt; element.
&lt;/p&gt;

                  an optional attribute which can define the location of an introContent.xml file that represents the content of this page. When this attribute is defined, all children and attributes in this page element, except id, are ignored. This is because the content of this page is now assumed to reside in the xml file pointed to by the content file attribute. When resolving to the content of this file, the page with an id that matches the id defined in this page element is chosen.
This seperation of pages can be used when performance is an issue, as the content of a page is now loaded more lazily.&lt;br &gt;

Since 3.1, if the content of the external file is XHTML 1.0, then the page is rendered as is.

            <annotation>
               <documentation>
                  A valid URL to an external web site, a static html file, or an Intro URL that represents an Intro action. All intro URLs have the following form:  http://org.eclipse.ui.intro/&amp;lt;action name&amp;gt;?param1=value1&amp;amp;param2=value2 and will be processed by the intro framework.&lt;br&gt;
The predefined actions will be described using this format:&lt;br&gt;
&lt;p style=&quot;margin-left:15px;&quot;&gt;
&lt;b&gt;action name&lt;/b&gt; - descripton of action&lt;br&gt;
&lt;i&gt;action parameter1&lt;/i&gt; - description of parameter&lt;br&gt;
&lt;i&gt;action parameter2 (optional)&lt;/i&gt; - description of parameter&lt;br&gt;
&lt;i&gt;action parameter3 (optional) = (&quot;true&quot; 
 &quot;false&quot;) &quot;false&quot;&lt;/i&gt; - description of parameter, choice of either true or false and &quot;false&quot; is the default&lt;br&gt;
&lt;/p&gt;

&lt;br&gt;
The following predefined actions are included in the intro framework:
&lt;p style=&quot;margin-left:15px;&quot;&gt;
&lt;b&gt;close&lt;/b&gt; - closes the intro part&lt;br&gt;
no parameters required&lt;br&gt;
&lt;br&gt;

&lt;b&gt;navigate&lt;/b&gt; - navigate through the intro pages in a given direction or return to the home page&lt;br&gt;
&lt;i&gt;direction = (&quot;backward&quot; 
 &quot;forward&quot; 
 &quot;home&quot;)&lt;/i&gt; - specifies the direction to navigate&lt;br&gt;
&lt;br&gt;

&lt;b&gt;openBrowser&lt;/b&gt; - open the url in an external browser. Since 3.1, this action relies on the workbench Browser support. This means that any user preferences set for the browser will be honored.&lt;br&gt;
&lt;i&gt;url&lt;/i&gt; - a valid URL to an external web site or a local HTML file&lt;br&gt;
&lt;i&gt;pluginId (optional)&lt;/i&gt; - if the url is relative, then it is relative to a plugin. Specify here the id of the plug-in containing the file.&lt;br&gt;
&lt;br&gt;

&lt;b&gt;openURL&lt;/b&gt; - open the url embedded in the Welcome page. In the case of SWT presentation, the url is displayed in an external browser (similar to the openBrowser action above). since 3.1&lt;br&gt;
&lt;i&gt;url&lt;/i&gt; - a valid URL to an external web site or to a local HTML file&lt;br&gt;
&lt;i&gt;pluginId (optional)&lt;/i&gt; - if the url is relative, then this specifies the id of the plug-in containing the file.&lt;br&gt;
&lt;br&gt;

&lt;b&gt;runAction&lt;/b&gt; - runs the specified action&lt;br&gt;
&lt;i&gt;class&lt;/i&gt; - the fully qualified class name of the class that implements one of &lt;code&gt;org.eclipse.ui.intro.config.IIntroAction&lt;/code&gt;,
               &lt;code&gt;org.eclipse.jface.action.IAction&lt;/code&gt;, or &lt;code&gt;org.eclipse.ui.IActionDelegate&lt;/code&gt;&lt;br&gt;
&lt;i&gt;pluginId&lt;/i&gt; - The id of the plug-in which contains the class.&lt;br&gt;
&lt;i&gt;standby (optional) = (&quot;true&quot; 
 &quot;false&quot;) &quot;false&quot;&lt;/i&gt; - indicate whether to set the intro into standby mode after executing the action&lt;br&gt;
additional parameters - any additional parameters are passed to actions that implement &lt;code&gt;org.eclipse.ui.intro.config.IIntroAction&lt;/code&gt;&lt;br&gt;
&lt;br&gt;

&lt;b&gt;setStandbyMode&lt;/b&gt; - sets the state of the intro part&lt;br&gt;
&lt;i&gt;standby = (&quot;true&quot; 
 &quot;false&quot;)&lt;/i&gt; - true to put the intro part in its partially visible standy mode, and false to make it fully visible&lt;br&gt;
&lt;br&gt;

&lt;b&gt;showHelp&lt;/b&gt; - Open the help system.&lt;br&gt;
no parameters required&lt;br&gt;
&lt;br&gt;

&lt;b&gt;showHelpTopic&lt;/b&gt; - Open a help topic.&lt;br&gt;
&lt;i&gt;id&lt;/i&gt; - the URL of the help resource. If the URL contains an anchor the sequence %23 should be used in place of the #&apos; character. (See Javadoc for &lt;code&gt;org.eclipse.ui.help.WorkbenchHelp.displayHelpResource)&lt;/code&gt;&lt;br&gt;
&lt;i&gt;embed (optional) = (&quot;true&quot; 
 &quot;false&quot;)&lt;/i&gt; &quot;true&quot; - indicates that the help resource needs to be displayed embedded as part of the Welcome pages. Default is false. This flag is simply ignored in the case of the SWT presentation. This is equivalent to openURL() command, but for Help System topics. The embedded URL occupies the full real-estate of the current page. since 3.1&lt;br&gt;
&lt;i&gt;embedTarget (optional)&lt;/i&gt; - the path to a div in the current Welcome page that will hold the content of the Help topic. If specified, then &lt;i&gt;embed&lt;/i&gt; is true by default and the embedded URL is inserted inside the div with the specified path. The path is relative to the page and so it should not start with the page id. The children of the div are replaced by the content of the URL. Only one div per page can be used as an embed target. This flag is simply ignored in the case of the SWT presentation. It is also unsupported when using XHTML as intro content. since 3.1&lt;br&gt;
&lt;br&gt;

&lt;b&gt;showMessage&lt;/b&gt; - Displays a message to the user using a standard information dialog.&lt;br&gt;
&lt;i&gt;message&lt;/i&gt; - the message to show the user&lt;br&gt;
&lt;br&gt;

&lt;b&gt;showStandby&lt;/b&gt; - Sets the intro part to standby mode and shows the standbyContentPart with the given input&lt;br&gt;
&lt;i&gt;partId&lt;/i&gt; - the id of the standbyContentPart to show&lt;br&gt;
&lt;i&gt;input&lt;/i&gt; - the input to set on the standbyContentPart&lt;br&gt;
&lt;br&gt;

&lt;b&gt;showPage&lt;/b&gt; - show the intro page with the given id&lt;br&gt;
&lt;i&gt;id&lt;/i&gt; - the id of the intro page to show&lt;br&gt;
&lt;i&gt;standby (optional) = (&quot;true&quot; 
 &quot;false&quot;) &quot;false&quot;&lt;/i&gt; - indicate whether to set the intro into standby mode after showing the page&lt;br&gt;&lt;br&gt;

If any of the parameters passed to these actions have special characters (ie: characters that are illegal in a URL), then they should be encoded using UTF-8 url encoding. To recieve these parametrs in there decoded state a special parameter, &lt;i&gt;decode = (&quot;true&quot; &quot;false&quot;)&lt;/i&gt;  can be used to force a decode of these parameters when the Intro framework processes them.&lt;br&gt;
For example, the following Intro url: &lt;br&gt;&lt;i&gt;
http://org.eclipse.ui.intro/showMessage?message=This+is+a+message&lt;/i&gt;&lt;br&gt;
will process the message parameter as &quot;This+is+a+message&quot;&lt;br&gt;
whereas&lt;br&gt;&lt;i&gt;
http://org.eclipse.ui.intro/showMessage?message=This+is+a+message&amp;amp;amp;decode=true&lt;/i&gt;&lt;br&gt;
will process the message parameter as &quot;This is a message&quot;.&lt;br&gt;

This is a dynamic version of the html intro tag. While the html tag allows for embedding or inlining a static html content into the generated html intro page, the contentProvider tag allows for dynamic creation of that content at runtime. 
Another difference between the tags is that the html tag is only supported for the HTML presentation, while this contentProvider tag is supported for both the HTML and SWT presentations. Since 3.0.1
