Re: Illegal Namespace prefix: "xml".

Brian Ewins Tue, 03 Jun 2003 00:02:07 -0700

I took a look at the crimson code causing this, its a bit odd. The exception being thrown is complaining about an illegal namespace declaration, not an illegal use of a namespace. (in Parser2.java)

if (attQName.startsWith("xmlns")) {
            // Could be a namespace declaration
....
if (!nsSupport.declarePrefix(prefix, value)) {
                error("P-083", new Object[] { prefix });
            }

My reading of all this is that the attribute named "xmlns:xml" is being read by the parser. Searching on google for similar error reports, it seems that every last one of them had extra xmlns:xml declarations; it seems crimson is ok with uses of xml: prefixes but barfs if you try to re-declare it.

This would suggest that the SOAP message causing the errors isn't the one Reto originally sent?

Per the XML spec[1], xml:lang is a special attribute. It is acceptable in
any XML document, and you aren't required to declare the xml: namespace
prefix. In fact, "xml" is a reserved namespace prefix name, so you can't
declare it. (Note that the error message is a SAX exception, and that it
says that the xml: prefix is "illegal" not "undeclared"). The schema that
defines <message> should declare the attribute (<xsd:attribute
ref="xml:lang" /> ), but I don't think that really matters in this case.

I'd say that this looks like a bug -- possibly in Crimson. It shouldn't barf
on the xml:lang attribute.

It appears that whomever is sending you this message is incorrectly

creating

it. The excerpt:
<message xml:lang="de-CH">
               null
           </message>
Contains a reference to a namespace prefix 'xml' which does not appear to

be

a 'defined' namespace for the document.
