Subject: Re: [ubl-dev] Duplicate Definition of Documentation Parameters


I believe it might be that you are trying
to get VS to create a data view, which
it can't do with UBL since UBL has
globally defined (reused) types. As long
as you don't ask VS to display or process
the schemas/instances as database schemas
or 'datasets' but just display the schemas
and instances as raw XML or in XML
(not data) graphical form I think it should
be fine.

All the best
