True, but FreeMarker is creating the XML parser and using it. I don't know if I have access to that SAX parser instance.

I don't really want validation and if FreeMarker isn't setting an error handler and handling the errors appropriately it should probably turn validation off right?

I wonder if I could register the DTD with the SAX API. I think this might also be an instance method.

The SAX API uses an ErrorHandler interface that is associated with the DefaultHandler sub-class passed to the parse methods. I think this is the issue. FreeMarker is setting the validation and not setting an error handler. I guess I might have to dive into the FM code for this stuff and figure out which SAX API it is using.  That is unless someone else has found a fix for this.
