One could use the same approach for namespaces:

- genxDeclarePrefix takes prefix and uri and returns an opaque reference
  (call just before genxStartTag at desired level)
- whereever you need this prefix mapping, just pass the reference to the
  API (genxStartTag, genxAttribute) instead of separate uri/prefix pointers
- to undeclare a prefix, call genxDeclarePrefix with a NULL uri
  (legal for default namespaces in version 1.0, legal for all namespaces in 1.1)
- to have a prefix auto-generated, call genxDeclarePrefix with a NULL prefix
  (but a non-NULL uri)
- to have a default namespace declared, call genxDeclarePrefix
  with the prefix "xmlns" (which is not a legal prefix)
