[jdom-interest] Re: attribute name "dt:dt"

[Alex Greif]

Hi,
Element elem = new Element( "catalog", Namespace.getNamespace( "xmlns:dt",
"myURI") );
throws an jdom exception: Namespace prefixes cannot contain colons

and
Element elem = new Element( "catalog", Namespace.getNamespace( "dt", "myURI") );
throws the same exception as at the beginning.

thanks
Alex.
