Arriverò al dunque :-):
Dice fra le altre cose ISO HTML (anno 2000, ultima revisione 2003):

2.1   Conforming documents
A document which conforms to this International Standard shall
1. Be a conforming HTML document consisting of a required document
type declaration, followed by a single document instance, contained
within an <HTML> [W3C 7.3] document element. The document type
declaration may be surrounded by white space consisting of RS, RE,
SPACE, TAB and HTML comments. The document instance may also be
followed by such white space.
2. Meet the requirements of this International Standard.
2.2   Validating systems
An HTML system is a validating HTML system if
   1. It is a validating SGML parser as defined by ISO 8879 subclause 15.4; and
   2. It is able to process any conforming HTML document; and
   3. It finds and reports an HTML error if one exits; and
   4. It does not report an HTML error where none exists.
2.2.1   Documentation of validating systems
Validating systems conforming to this International Standard shall
display the following identification text prominently and in the
national language of the documentation:
1. In a prominent location in the front matter of publications
(normally the title and cover pages),
2. On identifying displays of programs,
3. In promotional and training material.
The HTML validating system identification text is:
 An HTML validating system conforming to International Standard
ISO/IEC 15445—HyperText Markup Language, and International Standard
ISO 8879—Standard Generalized Markup Language (SGML).

NOTE: The validating system identification text is copyrighted by the
ISO/IEC, but may be used without further permission or further
reference to the ISO/IEC.
2.3   Conforming systems

A conforming HTML system is an HTML system which is able to process
all documents conforming to this standard.

Bastava adottare ISO HTML e non ci sarebbe stato alcun bisogno di
estenuanti discussioni sulla validazione, i parser validanti o meno,
il content type, e così via.
Qualcuno ha idea del perché questo non sia e sia stato fatto?
