/**
|
|
* <p>
|
|
* This is a pipeline component which performs XInclude handling, according to the
|
|
* W3C specification for XML Inclusions.
|
|
* </p>
|
|
* <p>
|
|
* This component analyzes each event in the pipeline, looking for <include>
|
|
* elements. An <include> element is one which has a namespace of
|
|
* <code>http://www.w3.org/2001/XInclude</code> and a localname of <code>include</code>.
|
|
* When it finds an <include> element, it attempts to include the file specified
|
|
* in the <code>href</code> attribute of the element. If inclusion succeeds, all
|
|
* children of the <include> element are ignored (with the exception of
|
|
* checking for invalid children as outlined in the specification). If the inclusion
|
|
* fails, the <fallback> child of the <include> element is processed.
|
|
* </p>
|
|
* <p>
|
|
* See the <a href="http://www.w3.org/TR/xinclude/">XInclude specification</a> for
|
|
* more information on how XInclude is to be used.
|
|
* </p>
|
|
* <p>
|
|
* This component requires the following features and properties from the
|
|
* component manager that uses it:
|
|
* <ul>
|
|
* <li>http://xml.org/sax/features/allow-dtd-events-after-endDTD</li>
|
|
* <li>http://apache.org/xml/properties/internal/error-reporter</li>
|
|
* <li>http://apache.org/xml/properties/internal/entity-resolver</li>
|
|
* </ul>
|
|
* Optional property:
|
|
* <ul>
|
|
* <li>http://apache.org/xml/properties/input-buffer-size</li>
|
|
* </ul>
|
|
*
|
|
* Furthermore, the <code>NamespaceContext</code> used in the pipeline is required
|
|
* to be an instance of <code>XIncludeNamespaceSupport</code>.
|
|
* </p>
|
|
* <p>
|
|
* Currently, this implementation has only partial support for the XInclude specification.
|
|
* Specifically, it is missing support for XPointer document fragments. Thus, only whole
|
|
* documents can be included using this component in the pipeline.
|
|
* </p>
