To briefly summarize an IRC conversation I just had with Norm -- in my
view this pipe succeeds iff some-imaginary-dns-name.tld serves
something in response to a GET for
http://some-imaginary-dns-name.tld/document.

The output of the XSLT2 step falls on the floor.

We discussed and rejected the idea of treating pipelines as document
management systems, allowing internal access to documents by name.  I
still don't want to go there.

However, the functionality Norm wants has general applicability, for
computing the input to existing mechanisms which take their 'inputs'
- From URIs, which include not only xinclude but also xsl:import and
xsl:include and possibly others.

Alternative suggestion:  give 'p:group' an input, call it 'cache', and
specify that any documents presented at that port must function as a
local cache for any http GET issued by any step inside the group's
subpipeline.
