  === Proposal for supporting WS-MetadataExchange on Axis2 ===
  
- Metadata Exchange is an implementation to support WS-MetadataExchange specification published
by IBM, Microsoft, BEA Systems, SAP, and Sun Microsystems. The WS-MetadataExchange specification
essentially allows for a service requester to issue a standardized request message that ask
for some or all of the metadata documents such as WSDL, XSD schema, policy associated with
a Web service. The request to issue is a Get Metadata request message. This kicks off a standardized
request and response MEP resulting in the delivery of a Get Metadata Response message.
+ Metadata Exchange is an implementation to support [http://schemas.xmlsoap.org/ws/2004/09/mex/
WS-MetadataExchange specification] published by IBM, Microsoft, BEA Systems, SAP, and Sun
Microsystems. The specification essentially allows for a service requester to issue a standardized
request message that ask for some or all of the metadata documents such as WSDL, XSD schema,
policy associated with a Web service. The request to issue is a Get Metadata request message.
This kicks off a standardized request and response MEP resulting in the delivery of a Get
Metadata Response message.
  
  To support incoming Get Metadata request message from SOAP protocol engines, Axis2 SOAP
processing is extended with new metadataExchange module, and allows plug-in of Data Locators.
Data Locator is responsible to perform data retrieval. The plug-in support allows other Web
Services engines that build on top of Axis2 to support different data retrieval implementation.
