Nope.  A default DTD does not imply a DOCTYPE.

DOCTYPE is mandated by W3C HTML standards, and its absence is an error.
I think the point was that the W3 validator treats that error as fatal,
and that that may be having a negative effect by turning novice users
away from validation altogether.

By contrast, Page Valet treats the error as non-fatal, and proceeds to
parse the page after reporting it.

Outside of HTML, there is no universal requirement for a DOCTYPE either
for SGML or XML.
