Sorry have to check... Have you got

<?xml version="1.0"?>

<?cocoon-process type="xsp"?>
<?xml-logicsheet
href="resource://org/apache/cocoon/processor/xsp/library/sql/esql.xsl"?>

at the start of the .xml page?

Oh, I've never done *THAT* 
</sarcasm>

In my case, it was a typo in the wrong spot that read something as http::/
instead of http://

Actually, this would be rather nice - something that says "Hey, this
namespace isn't any good!" durring the XSP processing...

BTW: Few days ago, I spent some (well, far too much) time finding
a typo in a namespace URI (one 'o' too many in 'cocoon' ;-)

It would have been helpful to get an error or at least warning
in this case. Would this be a job for Cocoon? Or Xerces/Xalan?
And is it this what's listed under 'wishes' on the TODO page?

that's the wrong namespace URI. sorry, trying to become consistent with
the cocoon2 namespace URIs.
