yes (i assume you talk about WSDL 1.1 SOAP document and rpc bindings)

assuming you want XML Schema validation for documents and as well to 
support SOAP encoding: i do not think that it is possible as there are 
different encoding rules in SOAP encoding than what can be described in XS

however if you do not care about XML schemas then all out there are just 
XML message and you can do anything with them.

all those ways to describe messages are contracts and if you make 
contracts flexible enough you can describe anything but then your 
contracts may be too weak for interoperability - how user can now what 
messages are accepted?

nice article about it that defines Web Service Contract as kind of

that will depend on your definition of platform independent  ;-)
