That's common misunderstanding.  HTML 2.0 specification [1] does
require conforming documents to start with a DOCTYPE declaration.
Here's an excerpt:

  3.3. HTML Public Text Identifiers

     To identify information as an HTML document conforming to this
     specification, each document must start with one of the following
     document type declarations.
     This document type declaration refers to the HTML DTD in 9.1, "HTML
        NOTE - If the body of a `text/html' message entity does not begin
        with a document type declaration, an HTML user agent should infer
        the above document type declaration.

The above note is for _user agents_, not for _documents_.  Besides,
this behavior is no longer recommended.  See [2] for details.
