Does some browser break if you render an &?
I created a simple html page (below) with both cases in an anchor and
they both seem to work fine in Firefox and IE 6:
---------------test.html---------------
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
