No.  The character "<" may not appear in any attribute value, either directly
or indirectly.  It can appear only through a character reference or a reference
to an entity (such as lt) containing a character reference.

Section 3.1, the WFC "No < in Attribute Values".  The reference to &lt; in this
constraint has been removed by an erratum.
