[wsrp-wsia] Create Issue: getMarkup() able to modify/return state

Topic:  interface
Class:  Minor Technical
Title:  getMarkup() able to modify/return state
Document Section: 6.1 Markup Operations
Description:
I keep hearing questions and discussions that raise this topic. The current
spec says that the getMarkup() operation is "for rendering the current
state of an entity". Is this the intended/agreed semantics? May the request
to render cause a protocol visible state change? Current spec limits any
such changes to the establishment of a session. Is this sufficient?
