[wsrp-wsia] Interface Issue: Entity property customization and usercontext

Topic:  interface
Class:  Minor Technical
Title:  Entity property customization and user context
Document Section: 7 Published State Interfaces
Description:

The current signature of setProperties and getPropeties takes a usercontext
as an argument implying that the properties returned by an entity may be
dependent on the user. This in turn implies that an entity is potentially
maintaining multiple property models, one per user. Such a concept seems to
conflict with the notion that an entity exposes a single set of persistent
properties for configuration.
