UMLNIEM3 — Clarify NIEMType

"Table 7-5 NIEM Components included in a NIEM Namespace" lists components. On page 53 it states "A class in a PSM with a «NIEMType» stereotype (i.e., one of the stereotypes listed in Table 7-5) applied shall". No reference is made to NIEMType regarding the table and its definitions.

Correct references to and in Table 7.5

Firstly, the quoted text in clause 7.3.1.3 PSM to XML Schema Mapping is incorrect: it should refer to Table 7.7, not 7.5. Secondly, in table 7.5, the reference to Class should refer to clause 7.3, not 7.2.3.
