Dear All,
I try to define a dsl which use some elements defined in an atl transformation.

So, using TCS injection of ATL, the textual representation of ATL transformation is generated as an xmi model conforms to ATL metamodel.
for example,

<?xml version="1.0" encoding="ISO-8859-1"?>
<xmi:XMI xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:atl="http://www.eclipse.org/gmt/2005/ATL" xmlns:ocl="http://www.eclipse.org/gmt/2005/OCL">
  <atl:Module location="1:1-391:2" name="S2F">
    <inModels location="5:2-5:27" name="SModel" metamodel="/48"/>
    <outModels location="3:2-3:31" name="FModel" metamodel="/47"/>
    <outModels name="SModel2FModel" metamodel="/1"/>
    <elements xsi:type="atl:MatchedRule" location="7:1-100:2" name="Process2Program">
.....
.....

Therefore, I try to refer in my dsl to some elements in the atl model.

I define an import:

import "platform:/resource/MetaModels/ATL.ecore" as atl

For example, a kind of xtext rule.

Affectation:
	reference  = ID '<-' rule=[atl::MatchedRule]
;

However, when I run the workflow, I have error (which is normal) because
"Could not find a GenModel for EPackage 'http://www.eclipse.org/gmt/2005/ATL'".

By contrast, ATL haven't a Genmodel (ATL.genmodel).

How can I resolve this problem, please.

Best regards,
