"""
Tests of input types.

TODO:
- refactor: so much repetive code (have factory methods that build xml elements directly, etc)

- test error cases

- check rendering -- e.g. msg should appear in the rendered output.  If possible, test that
  templates are escaping things properly.


- test unicode in values, parameters, etc.
- test various html escapes
- test funny xml chars -- should never get xml parse error if things are escaped properly.
