XPath 1.0 returned a set of nodes in no particular order; but XSLT 1.0
always chose to process these nodes in document order. People calling XPath
from other environments, e.g. a Java API, have tended to assume the nodes
will be in document order, and in practice they probably are, but the XPath
1.0 spec doesn't guarantee it.
