Thanks to David's help, I am now transforming xml that has a
namespace.  My target is a piece of HTML, so I would prefer if the
namespace was not in the output, which it is:

<div xmlns="http://www.photoparata.com/events.xsd"
xmlns:p="urn://www.photoparata.com/events.xsd" id="titlebar"/>

How do I go about getting rid of it?
