Universities are teaching it? That's a bit of a surprise. Which ones?
I'd be curious to now more about this.
However, I do know something about the developer books industry; and
from personal experience I can assure you:
1. Authors don't always bet on the right technologies.
2. The number of books published on a subject doesn't always indicate
the actual level of interest or potential success of a given technology
within the market.
3. The XQuery books that have been published have not done well in the
market, and you'd be hard pressed to get a publisher to commit to a new
one at this time.
Perhaps we're in the trough of the classic double bump adoption curve.
Past the initial hype excitement, and before actual practical
applications. If so things may pick up again, but it's hard to predict
the future. It may be that XQuery proves to be more like CORBA: a
technology that always had huge vendor interest and author support, but
never really came close to fulfilling what had been promised for it.
Time will tell.
