Certainly!  JDOM can edit your schema perfectly :-) That may not be what you
expected to hear.  A schema is parsed, and the document is parsed and
compared against that schema (depending on parser settings) long before a
JDOM document is ever built.  So, JDOM can use the underlying parser and
report schema violations that way. The specific schema version you need and
features depend on which parser you use so as long as JDOM has an adaptor
for a parser that supports your schema type, JDOM is usable with your

In memory validation against that schema within JDOM is not supported and
while the debate has not totally ended, I doubt it will be implemented.  The
main reason is that a complextype is not valid until the whole tree is
complete, but in JDOM you can build the parts completely independently.
