If there is no schema, then the message is not well defined. That means,
for instance, that you cannot predict whether elements repeat or may
nest. So, the fields may get validated some way (above types are NOT
schema defined types) but that is still a very weak message definition.

XML::Compile::RPC uses a home-brew schema to do about the same as the
above.

Probably, the only way to read these messages is via XML::Compile::Simple
or XML::Simple. To create these messages will require node-by-node
processing.
