in reply to Re^5: Passing 'SELECT MULTIPLE' parameters and CGI
in thread Passing 'SELECT MULTIPLE' parameters and CGI
XHTML does not impose any extra requirements on what the value is.
It does, actually. See the DTD:
<!ATTLIST select [...] multiple (multiple) #IMPLIED
That defines the 'multiple' attribute as having an enumerated set of possible values. Though in this case, there's not much enumeration to the set :)
EDIT: Actually, on re-reading, I guess I may just be agreeing with you...
