  please bugzilla this, provide a complete standalone xslt with the
associated xml input, this should like a bug and will be fixed.

  Depends how the input is parsed, the XML_PARSE_NOCDATA removes CDATA from
the input (because CDATA doesn't exist in the XPath data model used by XSLT)
and hence all CDATA are included as text nodes and adjacent text nodes
are automatically merged when parsed. If your python processes the tree and
not parse an instance, or if it lacks the XML_PARSE_NOCDATA option at parsing
then you won't see the same effect.
