Good. What other types does soap allow one to use/specify? 
Maybe using Java types is a good thing, but we should just discuss.

.. or maybe we need to functionality of a Ptolemy type object!?

that we need more discussions ;-)

Basically, the question was: if we add other type
mechanisms/assumptions such as Java types, C# types (just to be
"balanced") and PHP types, isn't that defeating the purpose of using
web services and WSDL (and thus also the reusability of those services 
in Kepler!) ?
