STYLE_SHEETS_USE test

Hi,

While we were reviewing the test implementation status in checker code,
we found out some checks 
of STYLE_SHEETS_USE regarding CSS values that we would like to comment
[1]:

[begin STYLE_SHEETS_USE fragment]

If the CSS Style contains a property with a value that is inappropriate
to it, warn
If the CSS Style contains a property with a value that requires a unit
or a percentage:
      If the unit (or percentage) is not present, warn
      If the unit (or percentage) is inappropriate to the value, warn

[end STYLE_SHEETS_USE fragment]

All these checks are already made during grammar validation test
(CONTENT_FORMAT_SUPPORT) and they would raise a *FAIL* (while in
STYLE_SHEETS_USE at most we would get a *warn*)
We do not see any benefit of this duplicity and, furthermore, due to
they raise different level errors, it might lead the user to confusion.


Regards,

Abel.
