I've started converting Ecore-Annotations to influence the hbm.xml and
DDL-Creation into the external persistence.xml to take care of
database-engine differences.

I've been successfull beside one minor thing. Using Ecore-Annotations
I've defined a Unique-Key on an EClass like this:

> >     <eAnnotations source="teneo.jpa">
> >       <details key="value" value="@Table(uniqueConstraints = {@UniqueConstraint(columnNames={&quot;LANGUAGECODE&quot;, &quot;COUNTRYCODE&quot;,&quot;VARIANT&quot;})})"/>
> >     </eAnnotations>
but I'm unable to port this over to the annotation.xml-File where I've
tried it like this:

> > 			<p:table>
> > 				<p:unique-constraint>LANGUAGECODE,COUNTRYCODE,VARIANT</p:unique-constraint>
> > 			</p:table>
But when generating this results in an CCE shown below:
