XMLSignature sign - avoid namespaces on every element

[Jasmin Wason]

Is there any way to stop the sign method of XMLSignature adding namespace
information to every element? When I use it the argument list in my SOAP
message becomes 7 times larger because namespace information is added to
every element. For long element lists this is causing an OutOfMemory error
because the SOAP message is too large. For example:   

Before calling sign:

    <soapenv:Body SOAP-SEC:id="Body">
        <ns1:WSMethod1
soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/";
xmlns:ns1="https://machine.domain:9443/MyApp/services/MyService";>
            <ns1:arg0 xsi:type="xsd:string">text1</ns1:arg0>
            <ns1:arg1 xsi:type="xsd:string">text2</ns1:arg1>
            <ns1:arg2 xsi:type="xsd:string">text3</ns1:arg2>

After calling sign:

    <soapenv:Body SOAP-SEC:id="Body" xmlns=""
xmlns:SOAP-SEC="http://schemas.xmlsoap.org/soap/security/2000-12";
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/";
xmlns:xsd="http://www.w3.org/2001/XMLSchema";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";>
        <ns1:WSMethod1
soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"; xmlns=""
xmlns:SOAP-SEC="http://schemas.xmlsoap.org/soap/security/2000-12";
xmlns:ns1="https://machine.domain:9443/MyApp/services/MyService";
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/";
xmlns:xsd="http://www.w3.org/2001/XMLSchema";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";>
            <ns1:arg0 xmlns=""
xmlns:SOAP-SEC="http://schemas.xmlsoap.org/soap/security/2000-12";
xmlns:ns1="https://machine.domain:9443/MyApp/services/MyService";
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/";
xmlns:xsd="http://www.w3.org/2001/XMLSchema";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:type="xsd:string">text1</ns1:arg0>
            <ns1:arg1 xmlns=""
xmlns:SOAP-SEC="http://schemas.xmlsoap.org/soap/security/2000-12";
xmlns:ns1="https://machine.domain:9443/MyApp/services/MyService";
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/";
xmlns:xsd="http://www.w3.org/2001/XMLSchema";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:type="xsd:string">text2</ns1:arg1>
            <ns1:arg2 xmlns=""
xmlns:SOAP-SEC="http://schemas.xmlsoap.org/soap/security/2000-12";
xmlns:ns1="https://machine.domain:9443/MyApp/services/MyService";
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/";
xmlns:xsd="http://www.w3.org/2001/XMLSchema";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:type="xsd:string">text3</ns1:arg2>

Is it possible to stop this from happening? Please let me know if this is
not normal behaviour for XMLSignature.sign(), maybe I'm doing something
wrong. Ideally this namespace information would just go in the WSMethod1
element and the subelements would inherit it.

A similar question was asked here

Any help would be appreciated.

Thanks,
