The underlying problem here is that DTDs don't allow you to make the set of required attributes for an element depend on the value of one of its attributes, so, because there are types of input element that naturally provide appropriate name text, input cannot make alt mandatory in the DTD. (Note there basically two types of tag in HTML: opening and closing. img, a, div, etc. are types of element. type, name, alt, etc. are types of attribute. image is an attribtue value.) Some of the crossposting may fail. Cross posting meiling lists is not a good idea. > -- David Woolley Emails are not formal business letters, whatever businesses may want. RFC1855 says there should be an address here, but, in a world of spam, that is no longer good advice, as archive address hiding may not work.
