           Summary: Validator incorrectly reports failure when using CSS2
                    grammar - parses full-length numeric escapes incorrectly
           Product: CSSValidator
           Version: CSS Validator
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: normal
          Priority: P2
         Component: CSS 2.0
        AssignedTo: ot@w3.org
        ReportedBy: cecil@cecilward.com

I believe that the following CSS2 fragment is legal CSS, if my reading of CSS 2
is correct, yet the validator incorrectly reports an error with grammar=CSS2
selected. Test case:

        selector { color: gr\000065en; }

Reasoning: in CSS2 no terminating space is required after a full-length numeric
escape sequence, filled out to the maximum of six characters. So in CSS2 the
property value is "red". See the productions for "escape" in the CSS2 grammar.


[FYI, compare 
        selector { color: gre\000065n; }
        selector { color: r\000065 d; }
both of which is correctly reported as valid. It seems to be that the parser is
reading characters after the sixth hex digit and parsing them as part of the
number.]

Regards,

Cecil Ward.
