Accessing Attr Constraints from Transf. Templates

[tthlivitis]

Hi,

This is about accessing attribute constraints (Attribute Constraints Tab information) from within Model 2 Model Transformation Templates.

Context:
I have already modified the XSD M2M Transformation Template to include some specific needs and I need to further enhance it in order to automatically read attribute length and pattern constraints described in a standard Class (not XSD) source model and generate equivalent tagged values in the XSD target model.

The current turn-around   is to use some unused but accessible attribute fields to describe the constraints (like initial value for the pattern constraint, or attribute alias for the length constraints) which is extremely non-intuitive for class modelers!  
Question

Am I missing some hidden hint about accessing attribute constraints from within Transformation Templates? Do you plan adding this possibility in the near future?

Thanks a lot.
