  and should be in 2.4.13 too.

  well I just gave a similar example where based on the XSLT spec semantic
it is clear xmlStaticCopyNode should not copy it (holding the xslt key
from the document node in _private).
  We are both right in our own use. There is 2 possible distinct semantics
and to avoid API explosion only a class based approach as suggested by
Simon would handle this correctly. But it's a large enhancement of the
set of API.
