[jdom-interest] writing XHTML

Wed Nov 12 10:13:16 PST 2008

It should be

Namespace.getNamespace("xforms", "http://www.w3.org/2002/xforms");

The "xmlns:" is not part of the namespace prefix.

It's a strange error message though: "Namespace prefixes cannot begin with
"xml" in any combination of case". What the specification actually says is:

<quote>
All other prefixes beginning with the three-letter sequence x, m, l, in any
case combination, are reserved. This means that:

    * users SHOULD NOT use them except as defined by later specifications
    * processors MUST NOT treat them as fatal errors.
