PerformerContextRole within SAF_Performer

[parkaneric]

For Sparx EA a following behavior was obeserved:

• When a SAF_Performer is part of an operational context a OperationalContextRole is created - which is correct.
• However, when SAF_Performer are organized in an hierchical manner using the Composition connector a OperationalContextRole is created within a (parent) SAF_Performer - whch is incorrect.

Further investigations in EA revealed that only one rule for instantiation is possible. When establishing a composition between an operational context and a performer an operational context role is created - the same applies when establishing a composition between two performer as the rule is defined with the SAF_Performer stereotype.

The issue is considered as a tool limitation. The following options are possible:

1. leave it as it is and add a note for EA users
2. rename the Operational Context Role to Operational Role as per NAF (which is appropriate for OCXD and OPRF VP)
