BACM — Rewrite the second paragraph of section 7.2.1 to clarify the relationship between the specification document and the normative XMI

The paragraph state:
For an implementation of the metamodel, the normative XMI that is part of this specification is intended to be an unambiguous and precise way to create an implementation that is equivalent to the underlying graphical predicate model. The non-normative XMI that is provided with the specification must be interpreted according to a set of rules to create a conforming implementation that is not based on MOF.
This paragraph is unclear and refers to a non-normative XMI that is NOT part of the specification.

Replace the second paragraph of 7.2 in its entirety

Replace the second paragraph of 7.2 -
"For an implementation of the metamodel, the normative XMI that is part of this specification is intended to be an unambiguous and precise way to create an implementation that is equivalent to the underlying graphical predicate model. The non-normative XMI that is provided with the specification must be interpreted according to a set of rules to create a conforming implementation that is not based on MOF."
with
"An implementation of the specification must conform to the metamodel expressed in the normative XMI file that is part of the specification. The diagrams in this document make use of stereotypes to eliminate detail that is present in the normative XMI file and make the diagrams more readable. The following paragraphs and subsections in this document explain how to interpret these stereotypes and how they are translated in the MOF-compliant, normative XMI file. In any case where the diagram and the interpretation rules appear to disagree with the normative XMI, the normative XMI is the authoritative source."
