Description Radomil Dvorak CLA 2005-12-13 13:21:19 EST 
Annotations from "http://www.eclipse.org/gmf/2005/constraints/meta" source can define meta-constraints and bind it to context. 
The context forms the environment for parsing the expression of a concrete constraint instance.

Add annotation semantics for declaring of custom variables which can be 
added to the context environment and be correctly resolved during parsing (validation phase).

It's useful for instance in link creation constraints where the client can reference the 'oppositeEnd' instance node by environment variable.
