Http MIME request through WCF service created in Biztalk

Can anyone help me with this i have no experience with MIME..

I created a service using WCF publishing wizard by publishing my schema and it works perfectly with SOAP+WSDL envelope messages, now i even need to  accept Http MIME multipart  messages through the service and send MIME response through the Service.

1.How can I accept the MIME messages?

2.can i use the same service and use the same endpoint?

3.once I accept the messages do i have to create a Custom pipeline component or can i use MIME decoder component in the pipeline

Below is my sample Http MIME header and body.

POST /core/eligibility HTTP/1.1
Host: server_host:server_port
Content-Length: 2408

Content-Type: multipart/form-data; boundary=XbCY
--XbCY
Content-Dis-data; name=“Type“
gdhs
--XbCY
Content-Dis-data; name=“PMode"
RT
--XbCY
Content-Dis-data; name=“PID"
e51d4fae-7dec-11d0-a765-00a0c91e6da6

Here is my sample schema which is working perfectly with the SOAP envelope

<ns0:In xmlns:ns0="http://BizTalk_Server_Project1.Schemareq">
  <Type>Type_0</Type>
  <PMode>PMode_0</PMode>
  <PID>PID_0</PID>
</ns0:In>

Thanks!!!!!!
