XProc processors that support only XPath 1.0 do not support any types
(or features) beyond those described in [XPath 1.0]. They use the
XPath 1.0 data model. Processors must implement all of the XPath 1.0
functions, but are not *expect" to implement the functions described
in [XSLT 1.0].

Question.
Is error XD0023 used when an xpath 2.0 expression is met by an
implementation which uses 1.0?
