           Summary: Including "impossible" requirements even as a SHOULD
                    is unnecessary
           Product: HTML WG
           Version: unspecified
          Platform: All
               URL: http://dev.w3.org/html5/spec/infrastructure.html#confo
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P3
         Component: HTML5 spec (editor: Ian Hickson)
        AssignedTo: ian@hixie.ch
        ReportedBy: adrianba@microsoft.com

The spec states that "Conformance checkers...should also check that the input
document conforms when parsed with a browsing context in which scripts execute,
and that the scripts never cause non-conforming states to occur other than
transiently during script execution itself. (This is only a "SHOULD" and not a
"MUST" requirement because it has been proven to be impossible.)

Making a requirement a SHOULD instead of a MUST if it has been proven
impossible is unncessary and should be removed. If there editor believes there
is a different recommendation to be made here, it should be worded
