Instead of using the XSLT document() function you could use the Include transformer (org.apache.cocoon.transformation.IncludeTransformer) which also supports caching. We use it successfully in our project.

We do use the cinclude transformer in the same project. But in this case i need to check the contents of the document before it can be included. This would require a few extra steps if we would use the cinclude transformer so that option is not preferable over the xpath document function.

For example:
<xsl:variable name="doc" select="document(@path)"/>
<xsl:if test="$doc/some-element">
 <xsl:copy-of select="$doc"/>
....

I think the XSLT processor should be aware of the catalog file in this case.

I ran into a problem with the catalog file and the xslt document() function. To include a document into the XML that flows through a Cocoon pipeline, I am using the document() function in an XSLT stylesheet: The document-to-include contains a DOCTYPE declaration referring to an external entity: <!DOCTYPE something PUBLIC "-//Company//DTD SOMETHING-XML//NL" "something.dtd"> I added the DTD-file to the directory WEB-INF/entities and added a line to the catalog file containing the PUBLIC and SYSTEM identifiers. The problem occurs when i use the document function to include the document directly with an absolute path, the catalog file is ignored, and the DTD is not found. To circumvent this, I was forced to redirect the document() function to a cocoon pipeline like this:

this should of course be
<xsl:copy-of select="document(concat('cocoon://get-file/', @path))"/>

instead of
   <xsl:copy-of select="document(@path)"/>

Cocoon reads the catalog and does not complain, so at least I have it working now. I was wondering (1) if this is expected behaviour (2) if there is another, more elegant way to solve this: can the XSLT processor be instructed to read the catalog somehow?
