You are passing in a string that contains markup. The XSLT processor
doesn't know that you want the "<" and ">" characters treated as markup,
so it escapes them.

There are two solutions.

(a) pass in a parsed XML document (e.g. a DOM) instead of a string.
(b) tell Xalan not to escape the special characters in the string by
using disable-output-escaping.

We usually discourage disable-output-escaping on this list, because it
can be greatly abused, but this is exactly the situation it is useful
for, when you want to include unparsed HTML directly into your
serialized output.
