The response is still
to change the module..
So the question is why
do we need sets?
Looking at the model
of State definition, how can a “State_transition” result in multiple
states?

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.

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
