SBVR16 — Define that Clause 10 ‘Fact Models’ are by Default Closed World Models

Spin-off from Issue 14843 (via Issue 15623 Issue Resolution into which it was Merged)
The definition-based model specified in Clauses 8, 9, 10, 12 and 13 and the fact model defined in Clause 10 are different (although closely related) models. The differences between them should be described and a transformation from one to the other defined. This would address two concerns:
1. Allow the definition-based model to have an open-world assumption and the fact model to have a closed-world assumption.
The proposed resolution is:
1. Define that Clause 10 ‘fact models’ are by default closed world models
