Matthias,
This isn't really a GMF question. What XSD type are these attributes.
They need to be xsd:anyURI or xsd:IDREF to become EReferences in Ecore,
and you'd need to use ecore:* annotations to make that happen.

I have converted a DTD to XSD using the trang tool. Then I tried to
generate a graphical editor using GMF. I am now facing the problem that
I do not know what to do with the CDATA attributes. One example: When
Mapping a class in the ecore model to a link with a link mapping, the
mapping needs a source and a target reference from the ecore model.
However, having generated the ecore from a DTD (where all those
references are just CDATA attributes), these references do not
reference node elements but are attributes of the type 'AnySimpleType'.
<br>
<br>
I could just change these to be references of the needed types, but I
need my saved files to have the same format as specified by the DTD
file. I thought of implementing an option to transform the saved file
to the DTD format with an XSLT, but nonetheless I wanted to ask if
there is a better way to handle this.
