MOF14 — Single-valued parameters should not be defined with sequences

Summary: If attributes with a datatype as their type are constrained
in the Model to disallow the cardinality of [0..1], as
recommended in a separate issue, then the handling of
parameters with cardinality defined as [0..1] can be
simplified, as compared to the recommendation in issue #940.

This constraint allows parameters with cardinality to be
treated as optional, single-valued parameters, instead of as
sets. The difference for clients and implementations is
significant.
