Ref: [[ hostname = domainlabel [ qualified ] qualified = *( "." domainlabel ) [ "." toplabel [ "." ] ] domainlabel = alphanum [ 0*61( alphanum | "-" ) alphanum ] toplabel = alpha [ 0*61( alphanum | "-" ) alphanum ] alphanum = ALPHA / DIGIT ]] I think the syntax production 'qualified' is ambiguous (i.e. permits more than one parse tree for some valid values). consider: .abc.def is this "." <domainlabel> "." <toplabel> or "." <domainlabel> "." <domainlabel> ? I think the production could be written thus: qualified = *( "." domainlabel ) [ "." toplabel "." ] ... Looking at this raises another test case for consideration http://example.123./aaa/bbb#ccc is this a relative URI or an invalid URI? I think the syntax says it's relative. #g ------------------- Graham Klyne <GK@NineByNine.org>Received on Wednesday, 26 February 2003 19:14:37 GMT
