[xsl] collecting a fileset with XSLT 2.0

[Mark Giffin <m1879@xxxxxxxxxxxxx>]

Is there a way to collect a set of files off the file system in XSLT 
2.0, in the same way that Ant lets you define a set of files with 
<fileset> like this:

<fileset dir="${src.dir}" id="all.docs">
<include name="**/*.xml"/>
<exclude name="**/gui/*.*"/>
<exclude name="tools/**/*.*"/>
<exclude name="content/extra/**/*.*"/>
</fileset>

Maybe an extension function or something? I've been using a 
manually-maintained list of files like this, but it's a a pain:

<docroot>
<root href="../../../doc_source/system100.xml" />
<root href="../../../doc_source/content/access/accesscore.xml" />
<root href="../../../doc_source/content/access/accesstest.xml" />
<root href="../../../doc_source/content/access/accesstest_commands.xml" />
  etc.
</docroot>

Thanks,
Mark
