   Both are defined at parse time, i.e. when taking a serialization
(in the form of a set of entities and trying to process them with
and XmL processor).

  Well XInclude processing is done at a time where *theorically* validation
has already been done.

  Of course in practice people want to validate after parsing, so 
I have added APIs to validate an already parsed document or validate
a document against a given DTD. I think all toolkits offers this but
this is not the canonical way of doing things.

  Libxslt and libxml are intimely tied since libxslt reuse libxml XPath
(and the general document and tree handling). I usually release them
together to avoid gaps, and try to force the dependancy in the RPM
packages and configure checks. But when packages are installed as .tar.gz
it would have to be tested by the library itself (doable, I could warn
if the library was used with a version of libxml different than the
one it was compiled against).
