SMM11 — Add relation to Scope Class

OMG Issue No: 15857
Title: Add relation to Scope Class
Source: Frédéric Madiot, MIA Soft,

Summary:
This issue addresses a lack of navigability in scopes.

Discussion:
Here are our modifications of SMM beta 2 specification:
Class Scope
we have added 2 references :
• a “non containment” reference called 'parent', type Scope (0..1), to link a scope to its parent.
• a “non containment” reference called 'children', type Scope (0..*), to link a scope to its children.

Summary of change:
• Add a new relation to Scope class:

o In the documentation for Scope, in the Associations sub-section, add the following new element:
children: Scope[0..*] Specifies the parent scope of this scope.
parent: Scope [0..*] Specifies the children scopes of this scope.

Discussion:
Reason for rejection: Scopes are sets and do not have a single inherent hierarchy.
Disposition: Closed, no change
