Allow attribute names identical to reactions keywords

[TomWerm]

Trying to access an attribute of a class (class[attribute]) which has the same name as one of the reactions keywords (e.g. to and from for a connection) does not work, as the attribute name is lexed or parsed as the keyword instead of the attribute.

Can you post an example? A test maybe...? Sounds like something I might want to try to fix.

We currently do not have metamodels that define attributes that have the same name as our keywords. The problem occurs if an attribute named, e.g., to has to be used. In the example:

after element network::Endpoint inserted in network::Connection[to]

the to would be parsed as a keyword and not as an attribute.
