Can a group of OMT object classes and interactions be identified within a BOM without expressing a Pattern Description?
Yes, its possible to identify the characteristics of a single conceptual entity without also having to define a pattern description. Keep in mind a BOM is intended to be used to represent and/or support a pattern of interplay. So if a pattern description is not included in the BOM, then it is anticipated that the BOM is a support element for one or more patterns of interplay.
