[jdom-interest] validating a schema

[Gregory S. Hill]

Is there a way to validate schemas using JDOM?  I used XML-Spy to create 
a basic schema from a SQL Server database, and then used JDOM to heavily 
modify it.  I would like to be able to verify that my modifications fall 
within the rules for schema construction, but doing it by hand would be 
somewhat problematic, as it is almost 5000 lines long!  It is, 
obviously, an XML file, as JDOM played with it very nicely.  I'm just 
not sure about its 'schemaness'.

Any help would be appreciated.
