Hi, All.
I have an XSD Schema with instances of Type A.
Now I would like to add a map, from A to A, where the key is a
refrerence, and the value is a containment.
I know how to do this in Java and in ECore, but not in XSD.
When I tried to load from the generated XSD fragment:
<xsd:complexType name="XMLToXMLMapEntry">
<xsd:choice maxOccurs="unbounded" minOccurs="0">
<xsd:element name="key" type="mtgDecoration:MXmlElement"/>
<xsd:element name="value" type="mtgDecoration:MXmlElement"/>
<xsd:element ref="xmi:Extension"/>
</xsd:choice>
<xsd:attribute ref="xmi:id"/>
<xsd:attributeGroup ref="xmi:ObjectAttribs"/>
<xsd:attribute name="key" type="xsd:string"/>
<xsd:attribute name="value" type="xsd:string"/>
</xsd:complexType>
It did not work, and it looks overly complex.
Is there any built in support in EMF/XSD for this?
Best Regards, Philipp

Philipp,
Here's what Ecore.xsd looks like:
<xsd:complexType name="EAnnotation">
<xsd:complexContent>
<xsd:extension base="ecore:EModelElement">
<xsd:sequence>
*<xsd:element maxOccurs="unbounded" minOccurs="0"
name="details" type="ecore:EStringToStringMapEntry"/>*
<xsd:element maxOccurs="unbounded" minOccurs="0" name="contents"/>
</xsd:sequence>
<xsd:attribute name="source" type="ecore:EString"/>
<xsd:attribute ecore:opposite="eAnnotations"
ecore:reference="ecore:EModelElement" ecore:transient="true"
name="eModelElement" type="xsd:IDREF"/>
<xsd:attribute ecore:reference="xsd:anyType" name="references">
<xsd:simpleType>
<xsd:list itemType="xsd:anyURI"/>
</xsd:simpleType>
</xsd:attribute>
</xsd:extension>
</xsd:complexContent>
</xsd:complexType>
* <xsd:complexType ecore:instanceClass="java.util.Map$Entry"
name="EStringToStringMapEntry">
<xsd:attribute name="key" type="ecore:EString"/>
<xsd:attribute name="value" type="ecore:EString"/>
</xsd:complexType> *
If you know how to do it in Ecore, you can try exporting the .ecore to
an XML Schema and see what it produces. I've tried to make the Ecore ->
XML Schema -> Ecore be as roundtrippable as possible...

Philipp,
There's this
http://www.eclipse.org/emf/docs/overviews/XMLSchemaToEcoreMa pping.pdf
but it's out of date and it doesn't specifically cover maps, although
there aren't really any map specific annotations, you just use general
purpose annotations to achieve a map result...
