[wsrp-wsia] [change request #251] Delete access control statement

Document: Spec v0.92 

Section: 9.3 

Page: 61

Requested By: Alejandro Abdelnur

Old text:  "Additionally, a Producer MAY can implement access
control 

programmatically through the use of facilities such as an authenticated

user identity."

New text: delete

Reasoning: WSRP does not define how the authenticated user identity is

propagated.
