  yes replace the prefix in the xmlNs. Check if it doesn't come from the
document dictionnary, if no xmlFree() it, and then replace it by a new
xmlMalloc'ed string or by a string from the dictionnary.
  The operation has no public entry point, usually namespaces are immutable
as the prefix should not be important and changing the namespace name affects
all referencing nodes in the document.
