A basic requirement for writing XML (and XSLT is XML) is to represent
all '<' that are part of the data (element or attribute or other) as
&lt;

Another characters in the same category is '&', which must be written
as &amp. when it is a data character (and not part of a character
reference that begins with '&').

(You may also find '>' written as &gt;.)

There's also a construct known as CDATA section, which is a general
"escape" mechanism for element data. See /bookstore/book[2] for
details ;-)
