<?xml version="1.0" encoding="utf-8"?><xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" attributeFormDefault="unqualified">    <xs:element name="Response">        <xs:annotation>            <xs:documentation>root element</xs:documentation>        </xs:annotation>        <xs:complexType>            <xs:sequence>                <xs:element name="TxDate" type="xs:string"/>                <xs:element name="TransactionId" type="xs:string"/>                <xs:element name="ActionCode" type="xs:string"/>                <xs:element name="BankCode" type="xs:string"/>                <xs:element name="PatientID" type="xs:string"/>                <xs:element name="IDType" type="xs:string"/>                <xs:element name="IDNo" type="xs:string"/>                <xs:element name="Name" type="xs:string"/>                <xs:element name="TransferKey" type="xs:string"/>                <xs:element name="ResultCode" type="xs:string"/>                <xs:element name="ErrorMsg" type="xs:string"/>            </xs:sequence>        </xs:complexType>    </xs:element></xs:schema>
