I remember that this issue was raised also in the past. I think the best 
way to proceed for GLUE 2 is to shape it as a use case to be added in 
the document.

When we will move to attribute definitions driven by use cases, then 
we'll address it.

Can you take care of that?

for GLUE 1.3 I take a note and then I'll verify it together with Stephen 
comments.
