Thomas B. Passin <tpassin@comcast.net> asks (among many other things):

I'd propose that an XPath statement in general can be considered the XML
equivalent to a view...
Well, that works at least to some extent, given that a view is generally
based on an SQL select statement, and a "select='{xpath_expression_here}' is
something like. What about xslt expressions that go beyond what you can
cram into a single xpath expression? What about a whole stylesheet? If
some stylesheet results could be considered equivalent to a view, which ones
cannot?
Let's see, a view can combine data atoms from different tables, based on
some join conditions. Could an XML view could combine infoset items from
different documents, or just from different elements within a single
document?
