Nitin Handa commented on WSS-181:
---------------------------------

Hi Colm,

Realized that the issue is with AXIS. It is optimizing namespace declaration

For eg, owsm signed below element
------------------------------------------------
<wsse:BinarySecurityToken 
xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd";
 
xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd";
 
EncodingType="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-soap-message-security-1.0#Base64Binary";
 
ValueType="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-x509-token-profile-1.0#X509v3";
 
wsu:Id="BST-2NQixJV5aafKsVvYq15hlw22">M+/8im3Pgzb3insPQq+N6BcQP9uiPv3fL/BDuIL</wsse:BinarySecurityToken>

But below element was sent somehow from oracle's webservices stack 
(after added default namespace):
------------------------------------------------
<wsse:BinarySecurityToken 
xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd";
 
xmlns="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd";
 
ValueType="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-x509-token-profile-1.0#X509v3";
 
EncodingType="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-soap-message-security-1.0#Base64Binary";
 
wsu:Id="BST-2NQixJV5aafKsVvYq15hlw22" 
xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd";>M+/8im3Pgzb3insPQq+N6BcQP9uiPv3fL/BDuIL</wsse:BinarySecurityToken>

While below element is received by wss4j : (realized that somehow AXIS 
is doing optimization and removed prefix to give preference to default 
namespace:
------------------------------------------------
<BinarySecurityToken 
xmlns="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd";
 
xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd";
 
EncodingType="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-soap-message-security-1.0#Base64Binary";
 
ValueType="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-x509-token-profile-1.0#X509v3";
 
wsu:Id="BST-2NQixJV5aafKsVvYq15hlw22">M+/8im3Pgzb3insPQq+N6BcQP9uiPv3fL/BDuIL</BinarySecurityToken>

I had a talk with web services team but they says that this should be ok 
for wss4j while doing exclusive canonicalization as they are also doing 
this as per standard specs so wss4j should also handle this.

Please let me know if anything can be done about this at wss4j end.

thanks
Nitin

> This same case is with STR and BST too..
