I don't think this should be an issue. I could have an element called
'person' in a WSDL having three annotations. First annotation could say
'ns1:Human', second annotation could say 'ns1:Resource', and third
annotation could say 'ns2:SpiritualBeing'. The first two are from the same
model and the third one is from a different model. It should not matter if
the annotations come from the same model or from a different model as far
as saying something about the semantics of the element 'person'. They
should all be treated independently. The same resolution that we arrived at
for issue # 3 ("identifying type of a model") applies as far as knowing
which semantic model the annotations come from. It's up to the tools to
figure out how they want to use these multiple annotations.

I think semantic annotations should be treated independent of one another
with no assumed relationships. It's up to the domain model to specify how
the concepts are related. Tools can inference the domain model and figure
out how they are related. For example, in the above example, there may be a
relation between 'ns1:Human' and 'ns1:Resource' in the domain model. It
should be left up to the semantic matching engines to inference and figure
out how they want to use it.
