I'm absolutely certain (100%) that it is /not/ a problem,
except in the minds of those who would like it perceived
as such.  HTML5 is the first real opportunity we have to
incorporate all the lessons we have learned from earlier
versions of HTML, and to ensure that adjunct technologies
(DOM, CSS, Scripting, etc.) are properly catered for.

To jeopardise this opportunity by insisting that the
browser use the same parsing/rendering algorithms for legacy
("tag soup") documents as for new ("well formed") documents
is insane, IMHO.
