In Gecko one can do it for example this way:
var dt =
   document.implementation.createDocumentType(
     "html",
     "-//W3C//DTD HTML 4.01//EN",
     null);
var doc = document.implementation.createDocument(null, null, dt);

This behavior is based on DOM 3 Core
"Note that based on the DocumentType  given to create the document, the 
implementation may instantiate specialized Document  objects that 
support additional features than the "Core", such as "HTML" [DOM Level 2 
HTML]."


IIRC, not all browser engines support creating specialized document
objects based on document type.
