What is relevant out of the model perspective?

But I suggest instead of restarting fruitless discussions about design 
principles, let us gather each the benefits we see compared to other 
approach.
For this purpose, I created this little nasty example with intersecting 
semantic, which might reveal a limitation of RDFa. But maybe Elias is 
able to solve it.

Correct. We should reuse as much as possible from existing features, but 
a consistent adding is not a reuse.
To me it seems it is easier to compare our approaches based on 
functionality and enabled scenarios.

Looking forward to compare the two lists of benefits for RDFa and the 
xml:id only approach,
