****************************************************************
When WS-Security verifies an XML Digital Signature that uses
the http://www.w3.org/2000/09/xmldsig#enveloped-signature
transform algorithm and the signed element has attributes with
a namespace prefix, a 'Digest value mismatch' error similar
to the following may occur:
SAML Assertion signature is verified.Core validity=false
Signed info validity=true Signed info
message='null'(validity=false message='Digest value mismatch:
calculated: KCuNwlUAk5+G2PYb8fZ+Y1hTMtw='
uri='#Assertion-1234' type='null')

Problem conclusion

If an element to be signed contains an attribute with a
namespace prefix the WS-Security is improperly canonicalizing
the element before calculating the digest value.

The WS-Security runtime is updated to properly handle element
attributes with namespace prefixes.

If the application of this APAR is causing compatibility
problems in a cell that has application servers at different
fixpack levels, you can return the runtime to the previous
behavior by doing the following:

Set the following JVM system property:

com.ibm.wsspi.wssecurity.dsig.enableEnvelopedSignatureProperty=t
rue

Set the following WS-Security custom property in the Inbound,
Outbound, or Inbound and Oubound custom properties in the
WS-Security policy set bindings:

com.ibm.wsspi.wssecurity.dsig.oldEnvelopedSignature=true

If you are using the SAMLTokenFactory to create a SAML token,
set the JVM system property and set the property shown above
in the SAMLIssuerConfig.properties file.

The fix for this APAR is currently targeted for inclusion in
fix packs 7.0.0.23 and 8.0.0.4.  Please refer to the
