Thanks Jeff and Helder,
I can see what your doing and it works nicely. I'm sure you can
appreciate the advantage of the SVG DOM accomplishing this with two
simple requests, rather than each of us building our own utilities.

I would like to refine these two method suggestions [let's call them
svgString() and svgElem() ]:

var mySVGstring=mySVGelement.svgString()
var newSVGelement=mySVGdoc.svgElem(mySVGstring)

The mySVGstring is an xml string that can be replicated as an SVG
element  in any defined SVG document:

var newSVGelement1=mySVGdoc1.svgElem(mySVGstring)
var newSVGelement2=mySVGdoc2.svgElem(mySVGstring)
var newSVGelement3=mySVGdoc3.svgElem(mySVGstring)
Append the elements where needed in the various documents.

The above also bypasses the need to work with Document Fragments as
required in Adobe's parseXML().


P.S. Jeff, it would be helpful if you suggested one or more of your
nice utility functions in this thread.
Just change the Subject to:
 Re: DOM APIs - <your suggestion title here>
Write your suggestion
and start it by sending it to: www-svg@w3.org
