1.7 Architectural References and Background reads in part: ***** WS-Calendar and this WS-Calendar PIM assume incorporation into services. Accordingly it assumes a certain background of definitions and discussion of roles, names, and interaction patterns. This document relies heavily on roles and interactions as defined in the OASIS Standard Reference Model for Service Oriented Architecture [SOA-RM]. ***** Does "relies heavily on roles and interactions" [lines 76-77] mean that this proposal normatively relies on SOA-RM? If so, SOA-RM needs to be under normative references and where appropriate, cited by section numbers.
