[Htmlvalidator-help] URI's and the accessibility validator

[Julian V. <ju...@va...>]

It's lovely to get the green tick mark when building a template, but
once it's applied to a web application, which uses variables in the
URI, the green tick mark disappears and gets replaced by the yellow
exclamation mark.

The reason is the HTML validator believes that the &'s used in the
URI's on the page should be escaped, when they absolutely shouldn't
be, in accordance with RFC2396 for URI's
http://www.ietf.org/rfc/rfc2396.txt

Could you please modify the HTML validator so that if the attribute is
an href="" or a src="", HTML character escaping is not tested, or
validated against a proper URI validator.

Hi Julian,

Unhappily, & needs to be escaped in cdata attributes. Please read this:

W3C spec:  http://www.w3.org/TR/html4/appendix/notes.html#h-B.2.2
W3C CDATA: http://www.w3.org/TR/html4/types.html#type-cdata
HtmlHelp: http://www.htmlhelp.com/tools/validator/problems.html#amp
Very interesting:
