I don't think so.  XPath defines comparisons in terms of the nodes'
string-values (possibly by converting to a number).

However, what the string-value for a particular element looks like
isn't defined.  If you use XSD or RelaxNG, you probably will use the
canonical representation of the lexical value in replies to
<get>/<get-config>.  IMO, this is something a "SMI for NETCONF" has to
address.

IMO, subtree filtering should also have been defined to not be
data-model agnostic, and instead compare the canonical form. which
depends on the type.
