This was a part of the XSLT 2.0 work -- XSLT 1 already supported
multiple XML inputs via the document() function, as well as text files,
and XSLT 2 adds the idea that any data source that can be represented in
terms of a shared data model can be processed by XSLT 2 and XQuery.

On the other hand, we (W3C) did not define explicit places to put, say,
SQL or SPARQL or other syntax to configure such inputs; for my own part
I'd be supportive of such an idea.

Outside W3C, such things can be done by groups of people -- e.g.
exslt.org -- and maybe even brought to W3C for standardization.
Within W3C, it's also possible, if at least two Member organizations
are sufficiently interested, to start a new "incubator group" to
investigate such things.

Having said all that, I also wonder whether XQuery isn't a better
starting-point for mashups... not because of differences in power
of the languages, but because of different focus of implementations.
