1. Currently, all port types does not have input and output name, except for Agreement port type:

<wsdl:input name="TerminateRequest" message="wsag:TerminateInputMessage" />
<wsdl:output name="TerminateResponse" message="wsag:TerminateOuputMessage"/>

The name attribute should be removed for consistency.

2. the names for message names, message element names and message type names are not totally symmetric

-- Agreement.wsdl

TerminateInputMessage <-> TerminateOuputMessage
TerminateInput <-> TerminateResponse (!)
TerminateInputType <-> TerminateOutputType

-- AgreementAcceptance.wsdl

AcceptAgreementInputMessage <-> AcceptAgreementOuputMessage
AcceptAgreementInput <-> AcceptAgreementResponse (!)
AgreementAcceptanceInputType <-> AgreementAcceptanceOutputType

RejectAgreementInputMessage <-> RejectAgreementOuputMessage
RejectAgreementInput <-> RejectAgreementResponse (!)
AgreementAcceptanceInputType <-> AgreementAcceptanceOutputType

-- AgreementFactory.wsdl

CreateAgreementInputMessage <-> CreateAgreementOuputMessage
CreateAgreementInput <-> CreateAgreementResponse (!)
CreateAgreementInputType <-> CreateAgreementOutputType

-- PendingAgreementFactory.wsdl

CreatePendingAgreementInputMessage <-> CreatePendingAgreementOuputMessage
CreatePendingAgreementInput <-> CreatePendingAgreementResponse (!)
CreatePendingAgreementInputType <-> CreatePendingAgreementOutputType

Solution:

TerminateResponse should be renamed TerminateOutput
AcceptAgreementResponse should be renamed AcceptAgreementOutput
RejectAgreementResponse should be renamed RejectAgreementOutput
CreateAgreementResponse should be renamed CreateAgreementOutput
CreatePendingAgreementResponse should be renamed CreatePendingAgreementOutput
