[wsrp-wsia] [change request #245] UserScope and caching

Spec 0.92/Section 6.1.5/Page 30/Lines 43-47

Old text: "If the Consumer does not know how
to process the specified userScope, it MUST NOT cache the markup."

New text: If the Consumer does not know how to process
the specified userScope, it MAY NOT cache the markup or it SHOULD handled
as *perUser* userScope."

Reasoning: I think it is to strong to require not
to do caching at all when the perUser scope would be a safe fallback as
it is private to the user.
