You should use a namespace for your controls:
like this:
<?xml version="1.0" encoding="ISO-8859-1"?>
<?xml-stylesheet type="text/xsl" href="/structure/foo.xsl"?>
<html xmlns:widgets="http://www.yourpage.com/namespace">>
<head>
<title>My title</title>
<link rel="stylesheet" type="text/css" href="/style/foo.css"/>
</head>
<body>
<widgets:specialwidget/>
</body>
</html>
And your xsl could match widges:specialwidget
Hope you understand. Learn more about namespaces too, its really cool
