Validator incorrectly reports validity for case of escaped close-quote which leaves quoted string unterminated

Test case checked using direct input mode, grammar CSS2 selected:

Test cases :


element { background-image: url("myimage\") ; }

element { background-image: url('myimage\') ; }

selector { font-family: "MyFont3\",  Serif;  }


I believe that the above examples are all illegal, if my reading of CSS 2.1
and CSS 2 is correct, yet the validator reports no error.

Reasoning: the escaped quote mark should be treated as _part of_ an
_identifier_, not as a closing string quote. See the productions for
"string1"/"string2" and "url" in CSS2 section D.2.
