    - CRLF semantics are different
    - << maps to <
    - These tags were added:
       <VERBATIM>, <NOFILL>, <PARAM>, <FLUSHBOTH>
    - These tags were removed:
       <COMMENT>, <OUTDENT>, <OUTDENTRIGHT>, <SAMEPAGE>, <SUBSCRIPT>,
         <SUPERSCRIPT>, <HEADING>, <FOOTING>, <PARAGRAPH>, <SIGNATURE>,
       <LT>, <NL>, <NP>
   This method implements them both.

   draft-resnick-text-enriched-03.txt is a proposed update to 1563.
    - These tags were added:
      <FONTFAMILY>, <COLOR>, <PARAINDENT>, <LANG>.
    However, all of these rely on the magic <PARAM> tag, which we
    don't implement, so we're ignoring all of these.
   Interesting fact: it's by Peter W. Resnick from Qualcomm (Eudora).
   And it also says "It is fully expected that other text formatting
   standards like HTML and SGML will supplant text/enriched in
   Internet mail."
