Ballot comemnt about state

The following ballot comment was made against the state modules.

I am not sure that it was discussed in Seattle.

What do people think?

Should the state_transition subtypes be able to relate sets of state_definitions?

If this is a PLCS requirement, then I propose that we reject the comment.

Ballot comment DE-46, DE-45

The state_relationship attributes related and relating are SETs of states. This is very unusual in the overall STEP modeling (see also 10303-41 E.3 Relationship template: object_relationship). The semantic of subtypes of state_relationship becomes by this very questionable. Grouping of states can always be achieved by composition_of_state. We have to avoid redundant mechanisms to achieve things.(6) Proposal: Change attributes related and relating to be of type state (not SET of state).
