Wsdl validation fails for request message payload from custom schema

Question

Hello. I am having a problem which I cannot seem to work around. I have defined a schema to serve as a template for the request message payload of a bpel process. The schema is very simple:
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:logininfo="http://sru/logininfo" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:sru="http://sru/profile" targetNamespace="http://sru/logininfo" elementFormDefault="qualified" attributeFormDefault="unqualified">
     <xs:import namespace="http://sru/profile" schemaLocation="http://sru/profile.xsd"/>
     <xs:element name="logininfo" type="logininfo:logininfoType">
          <xs:annotation>
               <xs:documentation>Needed information for SRU Login</xs:documentation>
          </xs:annotation>
     </xs:element>
     <xs:complexType name="logininfoType">
          <xs:all>
               <xs:element name="email" type="sru:emailType"/>
               <xs:element name="password">
                    <xs:simpleType>
                         <xs:restriction base="xs:string">
                              <xs:maxLength value="32"/>
                         </xs:restriction>
                    </xs:simpleType>
               </xs:element>
               <xs:element name="product" type="xs:string"/>
               <xs:element name="ip" type="sru:ipType"/>
               <xs:element name="timestamp" type="xs:dateTime"/>
               <xs:element name="xpath" type="xs:string"/>
          </xs:all>
     </xs:complexType>
</xs:schema>
(The schema depends on another, which I have placed at the end of this message).
I import it into the bpel process designer with no problems.
Upon defining the payload of the request message type to be the {http://sru/logininfo}logininfoType, the WSDL file does not validate anymore:
Validating WSDL...
Validating E:\OraBPELPM_1\integration\jdev\jdev\mywork\SRU\BPELProcess5\BPELProcess5.wsdl
Schema type not found: QName(http://sru/logininfo, logininfoType)
Validate WSDL: has errors.
Any ideas?

IT would help if the people that are working this issue would post the resolve of their problems. Every post I see with this problem someone from oracle replies with needing the source project to replicate the issue and the thread dies....
