Not yet, this is a new feature.

Here are couple of suggestions on how to validate against XMLSchema:

1) Create your own parser configuration that includes all the
features/properties needed by XMLSchemaValidator. 
The configuration is needed, so you can easily reset()
XMLSchemaValidator. For examples, see dom.DOMRevalidationConfiguration. 

2) To specify location of the schema, you could:
   a) Use properties:
http://apache.org/xml/properties/schema/external-schemaLocation and 
     
http://apache.org/xml/properties/schema/external-noNamespaceSchemaLocation
   b) specify schemaLocation attributes at the root element

3) XMLSchemaValidator also implements impl.RevalidationHandler that
allows you to set baseURI relative to which the resolution of schema
location should occur. The handler also has an additional method to pass
characters as strings (instead of XMLString).

Note: this is experimental code: the implementation can be
changed/removed or modified. (So you might need to change your code in
the future..)
