[QVTO] Use metamodel mappings with nested packages [message #836704]

My M2M transformation relies on an ecore meta-model with nested packages:

package1 (nsURI: htttp://package1)
-package11 (nsURI: htttp://package1/package11)
--class1
--class2
--class3
-package12 (nsURI: htttp://package1/package12)
--class4
--class5

This meta-model is located within my development workspace.
Since I want to deploy the model transformation also within the development workspace, I set up meta-model mappings for the transformation.

This works if I map the toplevel package URI to the ecore location like this:

htttp://package1 mapped to platform:/resource/<plugin-id>/model/meta.ecore

However, using this mapping, I have to prefix all the classes within the transformation via package1::package11:class1 etc. Hence, I would like to map the nested packages. I tried it using the same approach as for Xtext:

htttp://package1/package11 mapped to platform:/resource/<plugin-id>/model/meta.ecore#//package1

But this mapping does not work. It still refers to the toplevel package.

Thanks for help in advance!
