[wsrp-wsia] [change request #28] Portlet validating user input

Document: WSRP spec
Section: 1.2.3
Page/Line: 10/23
Requested by: Alejandro Abdelnur
Old text:
Proposed text: [append] Note that use of such technologies does not 
relieve the need for a Portlet to validate the input data it receives.
Reasoning: Clarify that the use of technologies that push data validation 
closer to the user do not relieve the ultimate responsibility of the 
Portlet to do validation.
