I'm curious, Jonathan, because this corresponds to the integration 
thread I was posting to.  What are the cost benefits of X-Query 
over say, SQL?  Is this simply to be able to program to a document 
model API (ie, Infoset-based?)

Apart from the usual geek quibbling, it becomes increasingly 
important that the Infoset-based view or paradigm for creating 
clients become exposed and understood.  It is hard to convince 
someone used to HTML/ASP like systems that there is any advantage 
to moving on to XML unless this model is understood in terms of 
its advantages.   Why swap out working data access tools for new 
ones if the old ones are doing the same job?  I watched the 
video from the MS project manager cited here last week, and it 
all sounds marvelous (eg, XML data documents, etc), but nowhere 
did I get a good sense, other than support, or why I should 
move away from MDAC and embrace this Infoset-centric world.

So why do it?  Benefits?

It's quite true that XQuery is more complex to implement than an XML 
parser. That's a way of measuring cost. It's also true that a car is more 
expensive than a bicycle. I would only buy a car instead of a bicycle if I 
thought there was a benefit to doing so. Traditional cost/benefit analysis 
looks at both the cost and the benefit, not just the cost.
