DTD or Schema needed?


I’ve got an DTD upon I’ve created with the Schema Editor a Tamino schema.I’ve defined it in the database and erased the DTD.

When I try to process a new xml file for that schema I create a new DOM object and use readDocument(fileinputstream).At this point the DOM object is trying to get the DTD from the url specified in the xml doctype tag.


My question is: Once that I’ve defined a Tamino schema in the database can I use that schema for validating xmls without needing the original DTD?
(for example if the dtd url is no longer valid I can’t insert new xmls in the database?!?)
