Hello,

i would like to reuse the "documentation" element from the XMLSchema namespace.
I'm creating my Ecore model using the XSD first approach.

<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:ecore="http://www.eclipse.org/emf/2002/Ecore".../>

<xsd:import namespace="http://www.w3.org/2001/XMLSchema" schemaLocation="http://www.w3.org/2001/XMLSchema.xsd" />

<xsd:complexType name="Documentation">
<xsd:sequence>
<xsd:element ref="xsd:documentation" maxOccurs="unbounded" />
</xsd:sequence>
</xsd:complexType>
...
</xsd:schema>

When i try to reload this XSD into the Generator model i'm not able to reference a Generator model for the XMLSchema definition. However a Generator model for the XMLNamespace definition exists in the "org.eclipse.emf.ecore" plugin which i can reference. This one is imported from XMLSchema definition and used by the "documentation" element.

Is there also a Generator model for the XMLSchema namespace which i could reference?

Greetings

Oliver

I think that's a bad idea.

Then you'll need to drag in the whole XML Schema for Schemas model.

Indeed. There isn't one.

Yes, that's a schema I'd normally expect would be reused.

No. Build your own documentation support. Copy it if you need to, but
don't try to drag in a huge schema to use one part of it.

Hi Ed,

Thanks for your fast reply. In the meantime i threw away the idea of importing XMLSchema namespace into my schema for just using a little part of it.

Indeed the generated Ecore model of XMLSchema is very large and i would'nt want to live with this. Furthermore it isn't a dedicated part of my domain.

So i've defined my own documentation type.

Thank you for clearance.

Greetings from Berlin
Oliver
