Re: Duplicate errors on W3C validator are not found on HTML

A user today reported a confusing error message from the Validator,
claiming that she had duplicate ID values in a web page but these
duplicates were not visible when the document source was viewed in
a browser.  It transpired that her server was configured to send
different material depending as the user agent was :

 W3C_Validator/1.3 http://validator.w3.org/services

or one of the UA values more typical for a mainstream browser.

Would it be possible to add an option to the browser options
to allow a "Validate as :" option, where "as" could include
one or more standard browsers ?  That would allow for much
faster identification and confirmation of the source of the error(s).
