For bookmarking sake (and to help me track the concerns), this is an
attempt to break out the distinct aspects of the Base URI discussion

== GRDDL Source Documents ==

Where by GRDDL source documents, I mean the documents which correspond
to source against which the normative XPath statements are applied.
There is an issue of XPath not supporting XML Base mechanisms.  We can
introduce a notion of a Base URI which is 'top-level' only but follows
XML Base in how it is determined (at least with the starting point being
the assumption that there is no notion of a base 'inside'

== GRDDL Transform Source Documents ==

XSLT 1.0 is our 'first-class' GRDDL transform and (by virtue of
depending only on XPath) also has limitations on XML Base resolution.
However, it introduces a 'top-level' notion of the base URI of the
document entity which can be passed in to the API and is often assumed
to be the URI used to retrieve the source document.

== Resolution of Empty URI References in GRDDL Result RDF/XML ==

If the GRDDL transforms do not output the RDF concrete syntax with the
Base URI information embedded, then GRDDL itself needs to provide a
consistent Base URI (as the external context).  It would seem to follow
that the (default) Base URI in this case should the same as the Base URI
of the GRDDL Source Document (as determined by XML Base)

Though issue-base-param was 'spawned' by conversations on the second
category, the tests which was committed (and the corresponding
resolution) had more to do with the third category.
