Clarification on Example 8.8.4
I am trying to understand what is meant by 'URI_of_ds:Signature_goes_here', is it:
<eb:ErrorList eb:id= 3490sdo9  eb:highestSeverity= Error
eb:version= 1.0  SOAP-ENV:mustUnderstand= 1 >
<eb:Error eb:errorCode= SecurityFailure  eb:severity= Error
eb:location= xlink:href='//SOAP:Body/ds:signature'
xml:lang= us-en
>
Validation of signature failed </eb:Error>
</eb:ErrorList>  This doesn't look quite right to me (the eb:location=).  Anyone know how to fix it?  Also, the example has a comma after the
eb:id='3490sdo9',  I don't think the comma is needed.  Regards,  David Fischer Drummond Group.
