I sent an email to the list a couple of weeks ago explaining its purpose, it is connected with extending an enumerated value.  This was the most expeditious solution and the least controversial (at least I thought so :-)) and is certainly not cast in stone.

There are only three mechanisms of achieving this, as far as I am aware.  By convention (this way), by element substitution or by including schema instance information.

The reason it is in CF is purely an architectural decision, allowing referencing specifications to extend that type instead of incorporating the context one.  Again, this is not cast in stone.

I think there are still a few issues to be decided in this area, including the potential removal of the status enumeration from context or even whether to allow extension of status enumerations.  The mechanism used for extending status will certainly change to comply with the other decisions.
