-<conbody>
-<p>There are two different ways to associate XML files with DTDs or XML schemas.</p>
-<ol>
-<li>Direct association - The XML file contains either the name of a DTD in
-its doctype declaration (for example, <!DOCTYPE root-element SYSTEM " <varname>dtdfile.dtd</varname>"
->, where <varname>dtdfile.dtd</varname> is the name of the DTD file) or it
-contains the path of an XML schema in the schemaLocation attribute of the
-XML file root element (for example, <xsi:schemaLocation="http://www.ibm.com
- <varname>schema.xsd</varname>">, where <varname>schema.xsd</varname> is
-the name of the XML schema.</li>
-<li>XML Catalog entry - You can register DTD and XML schema files in the XML
-Catalog and associate them with a <varname>Key</varname> that represents
-them. You can then refer to a DTD or XML schema file <varname>Key</varname> from
-an XML file instead of referring directly to the DTD or XML schema file. An
-XML Catalog entry contains two parts - the Key (which represents the DTD or
-XML schema) and a URI (which contains information about the DTD or XML schema
-location).</li>
-</ol>
-<section><title>How an association works</title><b>Associating an XML file
-with a DTD </b><p>If an XML file is associated with a DTD, a DOCTYPE tag such
-as the following one is included in the XML file:<codeblock><!DOCTYPE root-name PUBLIC "<varname>InvoiceId</varname>" "<varname>C:\mydtds\Invoice.dtd</varname
->">
-</codeblock></p><p><varname>InvoiceId</varname> is the public identifier of
-the DTD file. It is used to associate the XML file with a DTD file (in this
-case, the DTD file is <varname>Invoice.dtd</varname>). If the public identifier
-InvoiceId corresponds to the <varname>Key</varname> of the XML Catalog entry
-for Invoice.dtd, then the <varname>URI</varname> of the XML Catalog entry
-(which contains information about the location of Invoice.dtd) is used to
-locate the DTD. Otherwise, the DOCTYPE's system identifier ( <varname>"C:\mydtds\Invoice.dtd"</varname>),
-which refers directly to the file system location of the DTD, is used to locate
-the DTD.</p><p> <b>Note</b>: You can also use a system identifier as a Key
-in an XML Catalog entry. If you use a system identifier as a Key, a DOCTYPE
-tag such as the following one is included in an XML file:</p><codeblock><!DOCTYPE Root-name SYSTEM "<varname>MyDTD.dtd</varname>"> </codeblock
-><p>where <varname>MyDTD.dtd</varname> is the system identifier that corresponds
-to the Key of an XML Catalog entry.</p></section>
-<section><b>Associating an XML file with an XML schema</b><p>If an XML file
-is associated with an XML schema, one or more schema location attributes are
-included in the XML file. The information in the schemaLocation is provided
-as a "hint" to the XML processor. The following examples show schemaLocation
-attributes.</p><p> <b>Example 1 </b><codeblock><purchaseOrder xmlns="http://www.ibm.com"
-xsi:schemaLocation="http://www.ibm.com C:\myschemas\PurchaseOrder.xsd">
-<shipTo country="US">
-...</codeblock> </p><p><b>Example 2 </b><codeblock><purchaseOrder xmlns="http://www.ibm.com"
-xsi:schemaLocation="http://www.ibm.com PO.xsd">
-<shipTo country="US">
-....</codeblock> </p><p>In Example 1, the schemaLocation 'hint' ('C:\myschemas\PurchaseOrder.xsd')
-refers directly to the file system location or URI of the XML schema. In this
-case, the schema file will be located by the XML processor directly.</p><p>In
-Example 2, the schemaLocation 'hint' ('PO.xsd') refers to an XML Catalog entry.
-PO.xsd corresponds to the <varname>Key</varname> of the XML Catalog entry
-for PurchaseOrder.xsd, and the URI of the XML Catalog entry (which contains
-information about the location of PurchaseOrder.xsd) will be used to located
-the XML schema.</p><p>In both examples, <codeph>http://www.ibm.com</codeph> in
-the <codeph>xsi:schemaLocation</codeph> tag is a URI that identifies the namespace
-for the XML schema.</p><p>You can also use a namespace as a Key for an XML
-Catalog entry. If you use a namespace as a Key, a schemaLocation tag such
-as the following one is included in an XML file:<codeblock><purchaseOrder xmlns:="www.ibm.com"
-xsi:schemaLocation="http://www.ibm.com po/xsd/PurchaseOrder.xsd "></codeblock></p><p>The
-schemaLocation attribute points to both the Key and the actual location of
-the schema.</p><p><b>DTD or XML schema resides on a remote server</b></p><p>Several
-functions in the XML editor, such as validation and content assist, require
-the availability of a DTD or an XML schema. The product documentation provides
-usage information for cases when the DTD or XML schema resides on your local
-machine. However, in many cases, the DTD or XML schema can reside on a remote
-server, for example:</p><p><codeph><!DOCTYPE Catalog PUBLIC "abc/Catalog"
-"http://xyz.abc.org/dtds/catalog.dtd"></codeph></p><p>Normally, this case
-poses no problem, because the DTD or XML schema can be retrieved from the
-remote server. However, if you are behind a firewall, and do not have a SOCKSified
-system, the workbench currently does not provide a way for you to specify
-a socks server for retrieving a DTD or XML schema. If you are unable to SOCKSify
-your system, the workaround for this problem is to retrieve a copy of the
-DTD or XML schema (using a Web browser, for example) and save that copy on
-your local machine. Then, you can either place a local copy in the same project
-as your XML file, or use the XML Catalog to associate a public identifier
-with the DTD's (local) location.</p><p><b>Note</b>: If you have an XML file
-associated with an XML schema or DTD that is elsewhere in the network, and
-you are working on a machine disconnected from the network, you can follow
-the steps described previously if you want to use content assist or validate
-your XML file. </p></section>
-<section><title>Advantages of XML Catalog entry associations</title><p>If
-you create a direct association between an XML file and an XML schema or DTD
-file, any time you change the location of the schema or DTD you have to track
-down and update all of the referencing XML files with the new location of
-the DTD or schema. If, however, you associate an XML file with an XML schema
-or DTD Key, then, when you change the location of the schema or DTD, you only
-have to update the XML Catalog entry, instead of each individual XML file.</p><p>For
-example, you have a DTD called "Building.dtd", which is associated with five
-XML files - Office.xml, House.xml, Apartment.xml, Bank.xml, and PostOffice.xml.
-You move the DTD file Building.dtd to a new location. If you have a direction
-association between Building.dtd and all the XML files, you will have to update
-the <DOCTTYPE> declaration in each XML file to reflect the new location
-of Building.dtd.<?Pub Caret?> If, however, you have an XML Catalog association,
-and all the XML files just refer to the Key of Building.dtd, then you only
-have to update the URI and all the XML files will point to the new location
-of Building.dtd.</p></section>
-<section><title>Updating an entry in the XML Catalog</title><p>After you have
-updated an entry in the XML Catalog, you might need to refresh the XML editor
-view so that it uses the new information. To do this, click the <uicontrol>Reload
-Dependencies</uicontrol> toolbar button <image href="../images/rldgrmr.gif">
-<alt>This graphic is the Reload Dependencies toolbar button</alt></image> and
-the view will be updated using the current XML Catalog settings. You only
-need to refresh the XML editor view when you have an XML file open that references
-the XML Catalog entry that was updated.</p><p>For more information, refer
-to the related tasks.</p><p>(c) Copyright 2001, World Wide Web Consortium
