Public review comment: 10.4.1.1 Disallowed Tags

[Subbu Allamaraju <subbu@bea.com>]

This section states that portlets MUST NOT use tags like body, head, 
frameset etc. There is a similar statement (SHOULD) in Sec 10.5 
regarding use of CSS styles not specified in the spec.

However, enforcing these requirements is not trivial, and has some 
expense (such as parsing markup, script etc.) involved. One example is 
producers acting as bridges between legacy applications and portals, and 
sites designed with no knowledge of portal semantics.

In particular, the conformance test kit has tests to report assertion 
failures when a producer does not enforce these conformance requirements.

I'm opening this comment to consider relaxing these statements to 
guidelines indicating that portlets not following these guidelines may 
not look/work correctly in various consumer applications.
