Ah, now I see your point; so squeezing multiple standalone schemata
programatically into the validation process.

Yes: Libxml2 :-)

With Libxml2 you currently need to create a combining schema which
imports both of your schemata. I.e. you can feed Libxml2 only with
one initial schema. If you need this and are using Libxml2,
I recommend opening a enhancement request at
http://bugzilla.gnome.org/buglist.cgi?product=libxml2.
I guess it could be done for really standalone schemata in Libxml2;
this means that they all need be complete, without any dangling
references.
