Since I now see that this seems to have been a kind of dispute and not an ommision I'll provide references to the standards below. - Forwarded message from Marc Lehmann [EMAIL PROTECTED] - in http://perl.apache.org/guide/browserbugs.html I read: Preventing QUERY_STRING from getting corrupted because of entity key names: http://my.site.com/foo.pl?foo=barreg=foobar, then some browsers will interpret reg as an SGML entity This claims this is a browser bug, which it isn't. Browsers are perfectly fine to interpret the reg as an entity when you embed this in the html source unquoted. I don't think so. The browser would be right to treat reg; as an entity, not reg. If it had proper heuristics for dealing with poor HTML, it'd detect that there is no ; in sight for the next n chars, or that reg= isn't the start of an entity it knows about, and it would treat the as a literal. However, I agree that people should try their best to write proper html. If the above url appeared in a link it should be encoded as http://my.site.com/foo.pl?foo=baramp;reg=foobar. I find that a lot of developers don't care the least about the html they output because they somehow despise it. Think twice: take out the html, what's left of your site ? XHTML clearly forbids such wrong constructs (won't even parse if you get it wrong) and that's cool. It's like use strict for HTML. -- robin b. In which level of metalanguage are you now speaking?

Either a client has heuristics to deal with broken stuff or it hasn't. If it does, I'd expect it to go the whole way on a simplistic case as the one above.

If netscape and mosaic had flagged syntax errors nobody would expect browsers to implement heuristics today :( It's a chicken and egg problem. See how Netscape 6 / Mozilla is being bashed by designers out there. They all think it's a broken browser because it won't take their broken HTML. It tries hard (if you don't put a doctype, or put an old one) to emulate Netscape 4 brokenness, but it can't go all the way. As a result all those people are not using it, and are telling everyone not to use it. When you think that most of the time those people are considered "experts" in HTML/the web by others around them you can tell that a browser won't get accepted if those braindead pseudo-experts aren't happy with it. The only way out is careful education, and that's going to take time. However, I agree that people should try their best to write proper html. If Especially since you can only choose between theoretically incorerct and in practise sometimes not working AND theoretically correct and working alway sin practise I think the choise should be clear ;) True. It's really easy to produce html that does whatever you want and is correct. And is accessible. The main argument I use when convincing people (and I have to do that a lot) is forward compatibility. If it's correct now it'll always be. Today's heuristics may disappear with the next browser version. somehow despise it. Think twice: take out the html, what's left of your site ?
