Title:  Entity property customization and sessions
Document Section: 7 Published State Interfaces
Description:
At the F2F, we have decided to expose properties only at the Entity level.
However, the relationship between property modification and active sessions
is not clear. For instance,
 1. is it possible to change the properties of an entity once active
sessions are established?
 2.If its possible to modify the entity properties after sessions are
established, can the sessions be invalidated by the entity ?
3. Can the opaque entity state returned by a getMarkup change even if
invoked with a session handle? The last question is related to the Issue
#94.
4. Do we need the provider to indicate when entity property modification is
allowed at design time?
