Just to muddy the waters further, the conformance rules say that an XSLT
processor must be able to use a stylesheet to transform a source tree to a
result tree. 

The word stylesheet is never defined (and it's sometimes used to mean a
single XML document - what I call a "stylesheet module" in my book - and
sometimes a collection of XML documents linked through xsl:include and
xsl:import) but the closest is in 2.2: "A stylesheet is represented by an
xsl:stylesheet element in an XML document". So the source and result are
trees, but the stylesheet is one or more XML documents. This is why I drew
the diagram on page 49 of my book the way I did.

Since this discussion is about whitespace in the _stylesheet_, not the
source document, I think this distinction is relevant.
