Actually, now that I think about it, these forms don't really work. For 
starters, there should not be a '#' preceding the id of the related 
item, for consistency with the "for" attribute as used elsewhere (e.g. 
<label>).

More importantly, there is probably no need for the value of the "for" 
attribute to be a URL. In any situation where a comment is about another 
web page, a link will be present on the page that the <comment> can 
reference. So the form in this case would be:

<a id="link-id" href="http://example.com">Example website</a>
<comment for="link-id">
This website has a lot of great resources and ideas.
</comment>

Hence the only valid usage for the "for" attribute would be as with 
<label>, i.e. for="id".
