SPMS13 — MultiplicityStyle options are discussed in Section 12.6, not in the locations where cause effect

Section 12.6 discusses Multiplicity of PINboxes and Equalities, but does so a bit oddly. While it may have made sense to discuss the topic in one place, the effects are seen in PINbox, Equality, and BindingGlyph classes. It probably makes more sense (particularly for PINbox, where the Stacked view is dependent not on an explicit enum, but on an implicit multiplicity of its instances association), to move this discussion into the relevant sections.

Only moving the PINbox discussion would be acceptable, but clarifying text ought to be added to Equality and BindingGlyph as well.

Leaving the bulk of the Equality and BindingGlyph discussion in Sec 12.6 would then make sense, and it, coupled with Sec 12.7, would make for a good set of topics for guidance on visualization techniques that do not directly rely on the metamodel. (Peeling & Coalescing in particular is a UX behavior that does not currently have a reflection in the metamodel.)

Provided forward pointing hints, instead of moving sections.

While moving the Multiplicity sections was an option, no edits were satisfying, and instead this approach makes the minimal change that accomplishes much of the same goal.

A forward hint is added to each of Sections 12.3, 12.4 and 12.5 that refer to Section 12.6. These inform the reader of an additional twist to each situation, that will be discussed in detail in 12.6.
