Building OpenURL formatted URLs in XSLT

URLs in the OpenURL format have '&'s

Pushing XML through an XSLT outputs html with URLs coded with &amp;  <--
exactly right with regards to XML not quite right with regards to OpenURL.
So how do I get a straight '&' out
Dumb question and there is no other application after the XSLT
