image fileref and xincludes

Hi there,

(Within FOP)
I was wondering if there is a way to reference images within an absolute URI xincluded file.

I know there exists the 

<xsl:param name="keep.relative.image.uris" select="1"></xsl:param>

parameter which (if included in the stylesheet customization) makes the fileref reference to be "literally copied" to the output fo-file, but then all images referenced in relative URI xincluded files are not resolved anymore

These absolute URI xincluded files are not absolute referenced on purpose.

They arise when resolving a file like so

somefile.xml:
...
<xi:include href="">
...

catalog.xml:
...
  <rewriteURI
        uriStartString="file:///docdir/"
        rewritePrefix="somerelativedir/" />
...

What I intend with this is to make many xinclude resolutions to depend on the catalog that is used on the xsltproc invocation.

This works, but fileref tries to look for a file in

../../home/user/many/directories/in/path/../working_directory/image/

which doesnt exist.

This only occurs for fo. Html processing resolves image files flawlessly.

So my problem could be resolved in any of these three ways

- Find an alternative way to make selective path resolution depending on the catalog used

- Making fileref resolution to behave just as xinclude referencing works

- Making fileref resolution for FO work just like it does for html

Many thanks in advance.

Saludos,
