I don't see anything wrong with a Web application using custom attributes 
(preferably clearly prefixed or in a custom namespace) to store 
information like this. But I don't see the value in making the attribute 
for such a case standard. It would restrict what you could do with it, for 
one -- say the Web app wanted to store just a number for the help. Or just 
a URI. Or two URIs. Or an IDREF. Or a string. If we had an attribute, we'd 
have to define what it was, thus either blocking innovation, or using up 
an attribute for no good reason.

Yes, all the things I listed are plausible solutions, that's why I listed 
them. But they're not good _enough_, IMHO.

I don't see the advantage of having a standard way of doing something 
non-standard. It wouldn't improve interoperability.
