Enforcing of constraints violations needs clarification

[jonathan-r-thorpe]

Currently there is no explicit conformance language around how an NMOS Node should behave if they receive parameter data that violates constraints for a property or method parameter.

The expectation is on a violation of constraints that the NMOS Node:

• will reject the attempt to Set (or SetSequenceItem, AddSequenceItem) with a ParameterError
• will reject a method call with a ParameterError

Currently this is not stated in the specification.
