[jdom-interest] TrAX feature strings

[Elliotte Rusty Harold]

JDOMResult has the following field:

public final static String JDOM_FEATURE =
                       "http://org.jdom.transform.JDOMResult/feature";

JDOMSource has:

   public final static String JDOM_FEATURE =
                       "http://org.jdom.transform.JDOMSource/feature";


Five years of teaching people about namespaces has made me extremely 
leary of using any string that starts with "http://" and isn't 
resolvable.  I suggest we change the features strings to something like 
these:

public final static String JDOM_FEATURE =
 
"http://www.jdom.org/org.jdom.transform.JDOMResult/feature";

public final static String JDOM_FEATURE =
 
"http://www.jdom.org/org.jdom.transform.JDOMSource/feature";

and then put a page there.

Alternately, we could make them something that clearlyisn't a URL such 
as "org.jdom.transform.JDOMResult/feature" and 
"org.jdom.transform.JDOMSource/feature". However, an unresolvable URL 
will confuse people.
