For this usage, the (ISO) schematron skeleton files include templates
that output xpaths (not using any prefixes) to the context of the
message. (It also has templates that make xpaths with prefixes, suitable
for human readable error messages, but in many XPath API, it's just
simpler to report something as
/*[10]/*[5]
rather than
/a:b[3]/c:d[2]
and then worry how to bind the namespace prefixes.
