In Axis2's WSDL11ToAxisBuilder.java, there is code that converts from multiple message parts like so

    <wsdl:message name="testMultipleSwAResponseMsg">
        <wsdl:part name="testOutputSwA" type="bons1:TestBO"/>
        <wsdl:part name="swaOutput1" type="xsd:hexBinary"/>
        <wsdl:part name="swaOutput2" type="xsd:hexBinary"/>
        <wsdl:part name="swaOutput3" type="xsd:base64Binary"/>
    </wsdl:message>

into XML Schema based ComplexType(s). Basically a new ComplexType is created with a XMLSchema sequence inside
which you would see all the 4 parts. During this processing there is a code path where we lose fact that xsd 
prefix is mapped to xml schema namespace and it ends up using a xs as the prefix instead of xsd and the 
subsequent issue with xs prefix not found. This happens bec ause the complex type is created in the top level 
wsdl which has no declaration for xmlns:xsd or xmlns:xs
