  Looks fine yes. Point 3) seems to indicate that an extra function to
set the flags of a parser context correctly might be useful (though

    Give an example, sounds strange.

    Hum, strange. I'm pretty sure it works well, I even have some XSLT test
cases for those.

    Yes they are if you give the parser the required flags to add them to
the tree.

   1) is obscure, I don't understand could be a problem in the way you
      initialize the namespaces in your context before even trying to run
      a query using the associated prefix
   2) sounds wrong or you have a too old version
   3) you did not initialize the parser to add them to the tree
      look at xsltproc.c

    If you provide the examples of the document and the query, yes this may
help but double check the points I raised first.

    Thanks,
