I agree.
I am minded to reject this ballot comment.
The module reflects what is in Part 56.
Part 56 is an IS standard. We recommend that they raise a SEDS against
the IR.

Assuming there is a business requirement
for sets of state_definition, you cannot simply
use composition_of_state_definition and meet the requirement, it's not the
same thing as a generic a grouping mechanism to produce sets of
state_definition.

Subject: [plcs-dex] 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).

Rob
