Surely the point of specifying a starting node would be to operate
on a sub-document so that in your example /part/book/index would
be invisible to the XSLT processing. Your 'equivalent' syntax requires
the whole document to exist in memory.
No, I think that the semantics is taht given a starting node that is not
the root of the document you can still traverse the entire document
using the ancestor axis (or just /) to get back to the top.
So the whole document is there, you just don't start at /.
