invalid html comment id and anchor name

As of HTML standard, it is invalid to have an anchor-name with a name="comment-$cid" and some other element like div id="comment-$cid". This is invalid because name and id share identical namespaces.
Much more invalid is it if two html elements have the same id: Advanced forum adds the div id="comment-$cid" even if there's already an identical a id="comment-$cid".
advf-forum-post.tpl.php

In comments, each comment has an a id="comment-$cid" which is created by comment.module prepending each post. Advanced forum adds the is for each comment.
See comment.module function theme_comment_view @1585.

Removing the id from the container div makes the comment content no more accessible based on cid as the css selector. I don't expect this was used in real world. The HTML will be valid then.

The problem is, that some old browsers don't support a id="". w3c suggests to add both id="" and name="" with the same values for compatibility in xhtml 1.0. However the name="" was invalidated with xhtml 1.1.

I'm not sure yet if Browsers like IE6, IE7, ... are capable of jumping to a id="" attributed link or if they still require name="" to be present. However this would be some comment.module issue and not advanced forum one.

It seems to me we should simply remove the comment-cid identifier in advf-forum-post.tpl.php
