Some argument for choosing <dl dialog> or <dl type="dialog"> instead of
<dialog>:

(1) Breakability:

[Relates to In IE, Firefox, Opera and Webkit ]

When used inside <dl> it is OK to not close <dt> and <dd>. But inside a new
element, such as <dialog>, legacy (aka current) user agents will make the first
element after </dialog> in the following example a child of the preceding <dd>:

    <dialog><dt>Name<dd>Word</dialog>
    <p>Paragraph.

Same goes for the following example, except that it becomes a child of the
unclosed <p>

    <dialog><dt>Name<dd>Word <p>Paragraph.</dialog>
    <span>span</span>

(2) Bug 7508: There is no reason to have different rules for where <dt> is
permitted when used inside <dialog> and when used inside <dl>.

(3) HIstory: HTML 4 reccommeds dialogs inside <dl>

(4) Future: As HTML developes, one might want to use <dl> for other types of
lists as well - an attribute solution sets a precedence for such extensions.
