Because `<' may appear in their literal form *only when* used as
markup delimiters (or within a comment, a processing instruction,
or a CDATA section), while you are not required to use &gt; to
represent `>' unless it appears in the string "]]>" in content,
when that string is not marking the end of a CDATA section.
See "2.4 Character Data and Markup" of XML 1.0 [1] for details.
