Hi, I am defining my Ecore model using schema definition. Within my Ecore
model, I'd like to reference/use the XSD Ecore model. To that end, I am
importing the namespace "http://www.eclipse.org/xsd/2002/XSD" and
corresponding schema definition. I was able to locate and use XSD.ecore
and XSD.genmodel to obtain XSD.xsd for this purpose.
My questions are:
1) Would this work?
2) Is XSD.xsd available somewhere so that there is no need to generate one?
3) Is there an alternative way to reference/use the XSD Ecore model from
within a schema based Ecore model?
Thanks,
Jianhua

Jianhua,
This sounds very tricky. Within a .xsd, it's really XMLSchema.xsd you
should be importing to make use of XML Schema constructs in your model.
XSD.ecore is the hand-implemented model for XMLSchema.xsd but it wasn't
arrived at using the XSDEcoreBuilder as is used for other .xsd based
models. So you might indeed be better to export XSD.ecore to XSD.xsd
and refer to that. I haven't tried either and don't know what kind of
problems you're likely to encounter...
