[MOBY-dev] JAX-WS BioMoby API (2nd round).

[José María Fernández González]

Hi everybody,
	although you cannot have an XML schema for MOBY messaging taking into account
the whole ontology (unless you regenerate it each time the ontology is
changed), you can create an XML schema which at least can be used to validate
the fixed part of MOBY messages, using xsd:any in those places where you can
put a MOBY object. Some years ago I wrote such schema, but I never checked
it... Perhaps it can be useful for someone, so I'm including it in this message.

	Best Regards,
		José María
