Subject: HTML DTD question & comment

I recently downloaded html.dtd, html-1.dtd, html-s.dtd and html-1s.dtd via
http://www.w3.org/hypertext/WWW/MarkUp/html-spec/html-pubtext.html 
I assume this is the "reference" set....

I have a question about the formal public identifiers for each of these
DTD subsets.  The file html.dtd, for example, contains the declaration

<!ENTITY % HTML.Version
        "-//IETF//DTD HTML 2.0//EN"

        -- Typical usage:

            <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML//EN">
            <html>
            ...
            </html>
        --
        >

My question: Is the seeming inconsistency between the entity
replacement text and the comment intentional, or has the comment not
been updated, or what?  I noticed that html-1.dtd uses the "2.0" version
of the public identifier to reference [I assume] html.dtd.

The long & short: can someone tell me whether I am OK trusting the
"HTML.Version" version  of the PUBLIC id?

     -----------

Also, a (picky) comment.  The element PLAINTEXT is declared as:
      <!ELEMENT PLAINTEXT - O %literal>
and the entity "literal" is declared as
      <!ENTITY % literal "CDATA"
        -- historical, non-conforming parsing mode where
           the only markup signal is the end tag
           in full
        -->

In view of the comment, shouldn't both of PLAINTEXT's minimization
indicators be '-'?

Just curious,
