No. Just it isn't maybe widely known yet. Read 
http://java.sun.com/xml/jaxp/dist/1.1/docs/api/ .

You can write :
javax.xml.parsers.DocumentBuilderFactory.
newInstance().
newDocumentBuilder().parse(File/InputStream)

and get back an or.w3c.dom.Document  without ever having touched a 
specific implementation. (Yes this works in Xerces 1.4.*)

But then you can also read the header of the javax. imlementation that 
Xerces comes with :
ATTENTION: THIS IMPLEMENTATION OF THE "JAVAX.XML.PARSER" CLASSES IS NOT 
THE OFFICIAL REFERENCE IMPLEMENTATION OF THE JAVA SPECIFICATION REQUEST 
5 FOUND AT 
http://java.sun.com/aboutJava/communityprocess/jsr/jsr_005_xml.html
THIS IMPLEMENTATION IS CONFORMANT TO THE "JAVA API FOR XML PARSING" 
SPECIFICATION VERSION 1.1 PUBLIC REVIEW 1 BY JAMES DUNCAN DAVIDSON 
PUBLISHED BY SUN MICROSYSTEMS ON NOV. 2, 2000 AND FOUND AT

And there we are again, back to our problem of duplicate classes. With 
the "standards" being so much in the flux, I suggest it's best you leave 
the user to choose which "standard" he wants/needs to use.
