RE: [xml-dev] XMLSpy and <key><keyref>

["Markus Seibold" <Markus.Seibold@gmx.net>]

Nada and everybody,
I tried for one more day and I still couldn't figure out how to make the
<key> work. 

I want to represent a recursive 1:n relationship for a database table
AdminUnit (i.e., AdminUnit State consist of many AdminUnits Counties).
I declared the <key> element in the context of <country> and specified the
XPath to the <AdminUnitName> element which should be the key. I then declared
the <keyref> in the context of the <SubAdminUnits> element and specified the
XPath to the <SubAdminUnitName> element which should be the foreign key
pointing to the primary key.

I also pasted a XML instance document at the end of this message. The
document validates in XMLSpy although I specified a non-existend
<SubAdminUnitName>.

I would really, really appreciate any help regarding the mistake I am making
here.

Thanks, Markus
