I'll throw out the use cases I'm looking at - using web services against 
heterogeneous data sources.  We have a number of data sources - RDBMSs, 
Excel docs, and proprietary formatted files - which we want to allow to 
be exposed via web services, i.e., provide services which queries the 
data sources and returns large XML docs.  Sometimes, these queries are 
for reporting purposes.  Sometimes, its to gather meta-data information 
for cataloging.  We hope that updates are added to XQuery so these same 
clients can someday submit XML via some service we provide and have it 
placed in the appropriate data source.
