IMHO, no - document should be valid _after_ xinclude processing,
so DTD must not have support for <xi:include/>.

DocBook DTD doesn't support 'xml:base' attribute from XInclude.

Yes, this attribute appear to content model, and useful for many
of included documents - 'xml:base' could be useful for getting
uniq values of 'id', uniq names of images in <graphics> in the
all set of documents.

Now DocBook DTD and stylesheets not have full support of modular
documents.
