The distinction is between RPC style and Document style Web services. With RPC style Web services the SOAP payload is an XML root element that represents an operation that encloses any number of elements that represent parameters.
With Document style Web services the SOAP payload is a single XML document usually defined in a separate XML schema. The SOAP binding and operation elements used in the WSDL have style attributes which can be set to either "rpc" or "document"
For more details see: Which style of WSDL should I use?

Same way you validate any other XML document - with a validating parser. Check out Processing XML with Java.

Yes, see:
Axis User Guide: Service Styles - RPC, Document, Wrapped, and Message

Other than that you may want to look at Patterns and Strategies for Building Document-Based Web Services.
