SPMSSR — Enhance PatternSection body to allow for more than raw strings as content

Consumers of SPMS have requested the ability to include diagrams, pointers to existing documents, etc., in the section bodies.

Allow PatternSection to contain richer content than a simple string.

Sec 8.1, final paragraph, page 9:

Change from:
Each PatternDefinition contains a list of these Roles, and a list of PatternSections. These PatternSections are prose entries that describe for a human reader the definition of the pattern as defined according to appropriate patterns communities that adopt SPMS.

Change to:
Each PatternDefinition contains a list of these Roles, and a list of PatternSections. These PatternSections entries contain prose, diagrams, or other necessary structured document contents to describe for a human reader the definition of the pattern as defined according to appropriate patterns communities that adopt SPMS.

Sec 8.1 Figure 3, page 10:
Replace with new Figure3.pdf (attached)

Sec 8.5, paragraph 1, first sentence, page 11:
Change from:
A PatternSection is a free-form prose textual description of a portion of a PatternDefinition.

Change to:
A PatternSection is a description of a portion of a PatternDefinition. The description may be free-form prose, diagrams, models, or a structured combination thereof. The body attribute of the PatternSection is a generalized MOF::Element to allow for a multitude of formats and data, although the most common is expected to be simple text.

Section 8.5, Attributes, page 12:
Change from:
body : String The contents of the PatternSection.

Change to:
body : MOF::Element The contents of the PatternSection.

Modification to SPMS1.1.xmi: Convert body element type from PrimitiveTypes.xmi#String to UML.xmi#Element
