This is either just a special case of entity resolution (in which case
it needs no further mention in this phase), or else it is a special
case of URI resolution (in which case it takes place both when
building the stylesheet, and when executing the doc() and document()
functions).

Other way round - the stylesheet must be compiled first, in order to
determine the whitespace-stripping rules to be applied when stripping
the source document.
I suppose that an implementation might build the source document in
two stages, but this seems illogical.
Also, in XSLT 2.0 - a source document need not be present, so building
it is an optional step.
