Why do we need the xsl:for-each on the document('').
This sets the context to be the root node of the stylesheet, so then the
unparsed-entity-uri() function acts based on that context. From the spec:
The unparsed-entity-uri returns the URI of the unparsed entity with the
specified name in the same document as the context node
This is very clever! Thanks for sharing it, Ken!

What is the standard way of getting the absolute path to a stylesheet
so that references in the result tree can be resolved relative to it.
Call the static-base-uri() function.
Sorry for not clarifyingl, does that work for XSLT 1.0, if not what does.
The example below shows you get the base URI of the stylesheet when using
XSLT 1.0. I've needed this when working with the OASIS specification
stylesheets.
I hope this helps.

Thanks Ken. 2 questions.
Does this cover the case where the stylesheet is invoked from a pi in
the source document.
