Anish,

R2745 in BP 1.1 [1] defines both the absence of SOAPAction or it's value 
as empty string as empty string in the HTTP header field. I interpret 
that as empty string is not a valid value and thus implicit Action 
header should be generated in the SOAP message if SOAPAction is either 
not present or present with an empty string.
