For better or worse, that's what "plaintext" was designed for.  From
the description of a very early version of HTML [1]:

    This tag indicates that all following text is to be taken litterally,
    up to the end of the file.

Such a behavior is not expressible in SGML, and this element has been
deprecated from very early days.  "5.5.2.1. Example and Listing: XMP,
LISTING" of RFC 1866 [2], a.k.a. HTML 2.0, noted as follows:

      NOTE - In a previous draft, HTML included a <PLAINTEXT> element
      that is similar to the <LISTING> element, except that there is no
      closing tag: all characters after the <PLAINTEXT> start-tag are
      data.

It was included in HTML 2.0 and 3.2 as a deprecated element for
backwards compatibility, and has been removed from HTML 4 [3].
Of course XHTML has no support for "plaintext", and you should never
use this element for new documents.  It's pretty much obsolete.
