Hi Pinaki,
actually I am a bit confused by the example given on the web page. In
the example I would have expected a uri element to be present within
the instances element (due to minOccurs=1) and the element singular to
be replaced by many-to-one at its first and by one-one at its second
appearance. Also, in the definition of singular-attr-type, to me, there
seems something like <xsd:element name="instance" type="instance-type">
to be missing within the choice. Or was the first singular meant to be
an embedded instead ?
More generally speaking, I am wondering whether you start redoing SDO
here to some extent. (One begins thinking of serialising the metamodel
of a persistence unit to an xsd and its entities to an xml following
that xsd; if we extend the metamodel by OR mapping information...).
Best regards
Rainer
