If you read the HTML specification you'll find that it makes reference to external specifications of URIs rather then define them itself. Just because something is a valid URI doesn't mean it's valid HTML. >I want to understand why this asymetry exists and why it is tolerated. >I really like SGML, and have used it successfully in a few projects, >(though I would not claim to know it in detail), but I cannot persuade my >collegues of its benefits whilst it forces the requirement to encode URLs >upon them. Why is that a problem? You have to encode ampersands in the content of, say, a BLOCKQUOTE or STRONG element; why do you care that you hae to encode them inside the href attribute to the A element? And why do you think this represents an asymetry? > [1] I found this term in the validator error help. Huh? Which validator? I wasn't aware that the W3C Validator had any help to speak of and the FAQs for the W3C Validator do not contain the term "asymetry".
