    Title: FW: ebxml message schema
    It is unfortunate that the contents of
     
     
    and
     
     
    do not match. I believe that both represent snapshots downloaded from some W3C site at different times.
     
    Now that XMLDSIG has become a W3C Recommendation, I don't think the ebxml-msg TC should keep some old snapshot of xmldsig-core-schema.xsd at the location
     
     
    I suppose the file
     
     
    is the official one that goes with the W3C Recommended version of XMLDSIG. I suggest that we modify msg-header-2_0.xsd to reference the above file. If we choose not to remove the file
     
     
    we should at least update it with the contents of

    Hi
    We have noticed that the xmldsig schema imported in the version 2 of the
    message schema has a different location from the one used in the cpa/cpp
    schema. This in itself is not a problem, however these schema’s definitions
    are different yet both use the same namespace. This plays havoc with our
    object mapping tool’s notion that same namespaces means similar schema defs.

    >From msg-header-2_0.xsd we get:
    <import namespace="http://www.w3.org/2000/09/xmldsig#" schemaLocation="http://www.oasis-open.org/committees/ebxml-msg/schema/xmldsig-core-schema.xsd"/>

    >From above location (snip)
    <element name="SignatureValue" type="ds:SignatureValueType"/>
    <complexType name="SignatureValueType">
        <simpleContent>
            <extension base="base64Binary">
                <attribute name="Id" type="ID" use="optional"/>
            </extension>
        </simpleContent>
    </complexType>


    >From cpp-cpa-v1_0.xsd we get
     <import namespace="http://www.w3.org/2000/09/xmldsig#" schemaLocation="http://ebxml.org/project_teams/transport/xmldsig-core-schema.xsd"/>

    >From above location (same snip) ?
    <element name="SignatureValue" type="ds:CryptoBinary" />
    <simpleType name="CryptoBinary">
        <restriction base="binary">
    ?       <encoding value="base64" />
    ? </restriction>
    ?</simpleType>

    Would you please consider giving a different namespace to the later version.

    Regards Ian & Leanne
