NEW ISSUE: Why is wsa imported in the WSDL?

[Anish Karmarkar <Anish.Karmarkar@oracle.com>]

Title: Why is wsa imported in the WSDL?

Description:
On page 49, lines 156-1358 in [1], there is a schema import of the wsa 
namespace in the wsdl:types section. Why is this needed?

Justification:
The wsa element/types are not used by the schema (embedded in the WSDL) 
or used in the definition of any of the message constructs. The only 
place it is used is for wsa:Action (as a WSDL 1.1 extensible attribute). 
To do that, it is not necessary to schema import the namespace.

Target: wsdl

Type: editorial

Proposal:
Remove the xs:import that imports wsa namespace.
