Dave and all,

Regarding Elliott's suggestion to use a XSLT process to harvest geometry 
data from the XML geometry tree and present it in the form most 
appropriate for reconstruction, I fully support this option.  If someone 
would write a specification for a prototype of this harvester, I would 
be happy to write it.  I have found with XML tools that it is a lot 
easier for people to modify it and extend it once something exists, than 
to create it from scratch.  If I write a prototype to report something 
like the absolute z-positions of all of the anode planes in the fdc, do 
you think people might extend it from there to make it fully functional?
