This is an archived snapshot of W3C's public bugzilla bug tracker, decommissioned in April 2019. Please see the home page for more details.
Section 2.1, 1st bullet, last sentence. Point of clarity "A Participant Type is grouping together those parts of the observable behavior that must be implemented by the same logical entity or organization" Up to this point, all the previous Types (Role Type, Relationship Type) have been defined in terms of "a party" whereas the definition of the Participant Type is in terms of a "logical entity or organization". There is no explanation on the relationship between "a party" and a "logical entity or organization". This explanation of a "Participant Type" needs to be related to "a party".
