This should probably be added to the FAQ, it's asked often enough.

In-memory validation is a TODO item and a feature we very much want to
have implemented.  No other XML libraries have it that I know of, and
it'd be great for JDOM to be the first.  As you can see in TODO.txt,
we'd like to have validation against a DTD, against a schema, and
against an arbitrary set of business rules.  We're looking for
volunteers to take on this effort.

The workaround in the meanwhile is to use the parser's validation
feature which requires serializing the document and reparsing it with
validation turned on.  It's not fast, but it gets the job done.  If you
want it fast, you should be the volunteer.
