You can use the any element to provide something
similar to a DTD's ANY content model, however, it must be done in conjunction
with namespaces. This enables you to include any well-formed XML content,
such as an HTML Web page that conforms to XHTML 1.0 syntax.
For example:
<element name = "MyWebPage">
<complexType>
<any namespace ="http://www.w3.org/1999/xhtml>
< minOccurs="1" maxOccurs="unbounded" processContents="skip"/>
</complexType>
</element>
The preceding schema fragment allows a <MyWebPage> element
to contain any well-formed XHTML data that appears in the specified namespace.
The following instructions were written for the Resource perspective, but
they will also work in many other perspectives.
To add an any element,
follow these steps:
- In the Outline view, right-click the content model that you want
to work with and click Add Any.
- Select the new any element.
- In the Properties view of the schema editor, for a namespace value,
you can select ##any (this allows any well-formed XML from any namespace), ##local (this
allows any well-formed XML that is not declared to be in a namespace), ##other (this
allows any well-formed XML that is not from the target namespace of the type
being defined) or ##targetNamespace (which is shorthand for the target
namespace of the type being defined).
- For a processContents value, you can select skip (the
XML processor will not validate the content at all), lax (the XML processor
will validate the content as much as it can), or strict (the XML processor
will validate all the content).
- The minOccurs value is the number of times
the any element must appear in an instance document. You
can select 0 if you want the element to be optional;
otherwise, select 1.
- The maxOccurs value is the maximum number
of times an any element may appear. You can select 0, 1,
or, to indicate there is no maximum number of occurrences, unbounded.
- Click the Documentation tab if you want
to provide any information about this element. The Documentation page
is used for human readable material, such as a description, and the App
Info page can be used to provide information for applications.
