error code namespace from extension: bug?

I was just browsing net/sf/saxon/functions/ExtensionFunctionCall.java in svn, and I
noticed the following code in iterate(): } catch (XPathException err) { String msg =
err.getMessage(); msg = "Error in call to extension function {" +
theMethod.toString() + "}: " + msg; XPathException err2 = new
XPathException(msg, err.getException()); err2.setXPathContext(context);
err2.setLocator(this); err2.setErrorCode(err.getErrorCodeLocalPart()); throw err2; }
I've never tested it, but does this mean that if an extension function throws an
XPathException with an error code namespace URI other than the default, the rethrown
err2 will have the originally thrown error code local part but the default namespace?
Can that be good? Chapman Flack

It's generally the case, I'm afraid, that the concept of error codes being in a
namespace is not really very fully implemented in Saxon. Although the exception object
can hold a namespace URI, it's very rarely used: it doesn't even appear in standard
messages. I'll fix this particular path for the next release, but there's a lot more
that needs to be done for namespaced error codes to work properly. Michael Kay
