+   RFC 1563 superceded text/richtext with text/enriched.
+   The changes from text/richtext to text/enriched are:
+    - 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."
