RE: Microsoft files for XML patents, says C|Net

Hi Rex,

It's probably not that serious. I'd say it's unlikely that this patent will
be granted and I'd be willing to bet that there are at least a 1/2 dozen
members of this list who could lay claim to some prior art. (See the bottom
paragraph for my layman's description of potential prior art).

I just responded to Bob Wyman's reply. You both have more experience 
and insight into this than I, and this appears to be a more 
potentially damaging development than I thought.

Ciao,
Rex
