Re: p:exec -- can it apply to only selected parts of input using a loop?

I was under the impression from the
http://www.w3.org/TR/xproc/#p.viewportthat it was solely used for
modifying nodes in a document but I suppose
within a subpipline in the viewport one can do what one wants with the
selected nodes such as,, store,, http-request and not change the selected
nodes at all.  Cool..

Well name aside I vote the xproc dev list could use some more examples of
viewport being used.
