I tried the modifications you suggested and got disappointing  
results.  I've posted the errors produced again at http:// 
www.ssec.wisc.edu/~brucef.

Your suggestions bring up a couple of questions regarding the schema:
 1. Is it correct that the order in the schema is the _exact_ order  
they must appear in the XML doc (if they appear of course)?
 2. where is the definition for datasetRoot?  It doesn't appear to  
be in the schema.
 3. there are some other elements, addDatasetSize for example, that  
also don't seem to be in the schema.

I see your point about the documentation.  A description with the  
additional xhtml anchor tag would probably work well, but I cannot  
seem to get that to work either.  The XML parser fails when it comes  
across the anchor.

Unfortunately, the server is running on a machine that is not  
available outside of SSEC.  If it would be helpful I can run a  
service on a machine that is available.

Thanks for your time,
Bruce
