UML25 — Clarification on the semantics of Properties

Title: Clarification on the semantics of Properties
Where: section 9.5.3
Nature of Issue: Clarification
Severity of Issue: Minor
Full Description of the Issue:

• AgregationKind: "if a composite instance is deleted, all of its parts are normally deleted" what does mean 'normally'? Which other case could arise?
• Does the definition of "composite" imply that an element can't be part of two composite instances in the same time? If yes, it should be stated so.

The word “normally” simply introduces confusion and should go.
Some rephrasing is required to clarify that all composed instances are called parts, and also to use appropriate
wording to clarify that the composition semantics only apply where the instances are objects.
