Thanks for your response.  The point I was trying to make is that
<dialog> is still making an association.  It associates (A) what is said
with (B) the person who said it.  The fact it uses <dt> and <dd>, the
same inner elements as <dl>, is evidence enough of that.  I was
suggesting that definition list had been confusingly specified in the
first place, and more clearly specifying an association list (either by
adjusting the specification for <dl> or by creating a replacement
element such as <al>) could better serve all purposes, including marking
up dialogue.

The reason for introducing a new element is precisely to avoid
<dl> at all.

I'm not really sure what you mean. <dialog> isn't related to <dl>.


...associates A and B with 1 and 2, and C with 3.

<dialog> is for marking up dialogue, and is unrelated to <dl>.

I don't think a dialog and a glossary are equivalent at all. <dl> is the

element for assocation lists. <dialog> is for conversations.
aren't association lists.

You can do that today:

   <h2>Coder's Glossary</h2>
    <dd>Hyper-Text Markup Language</dd>
    <dd>predominent markup language for web pages</dd>
    <dd>basic components for code markup</dd>

You can do that in HTML5:

    <dd>Why didn't you specify an association list?</dd>
    <dd>We did</dd>
