Great, thanks for taking a look at that. I realize that the SchemaWriter is
only experimental and I wouldn't have written in, except that I think the
namespace resolution in XMLType may be important in other areas. Definately
do not waste your time on the Writer on my behalf, I will do any changes
that I need. After I have done all of my own changes to the schema writer I
will definately submit them to you guys. In particular I am going to try to
add support for xsd:import.
Thanks
matt

Hi Matt,
I'll take a look at upgrading the SchemaWriter and adding the additional
namespace resolution you mentioned below. Keep in mind however that the
SchemaWriter is currently not supported. I only hacked it together for
testing purposes, which is why you need to explicitly enable it's usage.
:-)
Thanks,
