If your WSDL processor receives a value for SOAPAction then the processor
should resolve the SOAPAction value to the
operation/binding/port/portType/message(s)/part(s), e.g., regardless of the
actual value of SOAPAction the message intent and structure are known.
Caveat...*all* SOAPActions cannot be equal, e.g., unresolvable.

If you imported a WSDL, the SOAPAction value of "XXX" provides one of the
mechanisms for resolution of the imported WSDL regardless of its actual
value.  This is one of the more powerful aspects of WSDL whether document or
rpc style messages.
