.. versionchanged:: 3.5
Added the *context* argument.
.. versionchanged:: 3.6
Added support of type tags with prefixes (e.g.``ex:nil``).
Added support of unmarsalling additional types used by Apache XML-RPC
implementation for numerics: ``i1``, ``i2``, ``i8``, ``biginteger``,
``float`` and ``bigdecimal``.
See http://ws.apache.org/xmlrpc/types.html for a description.
