Re: Can default attibute values defined in xsd be referenced?

I'm very certain that FreeMarker exposes the default attributes just
like if they were there (except when using @@markup and like, but
that's not the case here). So perhaps the problem is with the way you
create the W3C DOM tree. For example, are you sure that the parser
that you are using is a validating one?
