Thanks Nitin.  I managed to get the IDOMAttr after getting the node by 
first checking to make the sure the node was in the namespace I expected 
and then getting the attribute by name, and comparing it's IDOMAttr 
ValueRegion ITextArea#getStart to the ITextArea#getStart I had.   So 
basically, I now I have a convoluted way of getting a node based on the 
ITextRegion.

Thanks for the tip.
