(sorry for the lateness of this response)

all of the elements in the form were created using SAX by a custom
component. the component strictly creates nodes in the default namespace:

handler.startElement("","form","form",attributes);

the other elements on the page were generated using SAX by cocoon's
FileGenerator, which is ultimately using jaxp (xerces) to parse the file.

a bit. would it be helpful if i got a dump of the SAX events that are
being given to xalan for debugging? if so, let me know. for the time
being, i've simply removed the namespace from that layer. i'm actually
finding that the more i use namespaces, the more i dislike certain aspects
of working with them.
