CWM12 — Modeling and packaging guidelines

Metamodels described in the CWM specification employ certain
modeling techniques and packaging styles in preference to others. However,
the current text of the specification does not clearly delineate, or provide
a rationale for, which modeling techniques and packaging styles are
preferred and which are not. Because stylistic consistency is an important
part of promoting both understandability and implementability, text should
be added to the specification (possibly in Chapter 6) delineating preferred
modeling techniques and packaging. Such documentation will provide guidance
to submitters of enhancements to existing CWM metamodels and of new or
replacement metamodel packges.
