I have some new information to this respect. As I dug further into
this I found the the Docbook 5 Macport bundles docbookxi.rnc which
adds XInclude support to the Docbook 5 bundled in the port. But IMHO
it should also include the XInclude schema and I wonder if this
problem comes from the FreeBSD port. The problem I see with not
bundling XIndlude as well is that whilst xsltproc (libxml2) supports
XInclude by means of the --xinclude switch I am not sure if all then
toolchains will work off-line without and explicit XSD and/or RCN file
and catalog entry for XInclude.
I will look further into this and contact the maintainers or file a
bug if need be.
