The FAQ says it allows some things UML doesn't.

"Plus sa change, plus la meme chose"

Interesting!  ConML reflects a lot of (my hero) Jean Raymond Abrial's seminal work of the 1970's "Data Semantics".  Semi-Associations (Abrial's "Access Functions"), The difference between Null (Nothing) and Unknown - which I have formalised into the concept of extrinsic values.  Links as relating instances of associations relating instances of classes.

A quick scan of the Specification leaves me with some ontological issues.  I think some things have been named incorrectly, but this may be due, in part, to translational issues.  A couple of things seem to be structurally anomalous.  But overall, a good start.

I think we should continue to discuss (and hopefully encourage Sparx provide an MDG).  Some of the concepts are already incorporated in our modelling environment (due, I guess, to my knowledge of Abrial's methodology).

I'm happy to discuss my views (no ironic responses please!  ;D), in order to better understand what the specification means and, where appropriate, incorporate aspects of the specification into our environment.
