XInclude is a schema that allows for complete document inclusions:

Most of these schemas are either accessible on-line or installed on a
system and uses an XML catalog to resolve URIs and local paths. In
MacPorts, this catalog is in /opt/local/etc/xml

Usually these schemas are installed as a dependency or bundled as part
of a port that needs them. For example if you intall GTK2 and Glade it
will include an XML schema that  is installed in /opt/local/share/xml
and registers itself in the catalog mentioned above.

I would have though that the Docbook 5 XML port would bundle XInclude
but it doesn't so I was wondering if it was in a separate port. As you
stated above, it seems that libxml2 and xsltproc somehow have XInclude
embedded and I ultimately solved my problem by adding the --xinclude
switch to the xsltproc command line. But I am curious as to why there
is no XInclude schema or RelaxNG equivalent installed or installable
via MacPorts.

Hope that answers the question.
