This clause describes some behaviour of IRPManager and IRPAgent not captured by XML Schema in File Integrity Solution.
6.1 File Integrity Solution
This clause addresses how to use XML Signature to provide File Integrity Security Service.
To Enable IRPManager and IRPAgent to use XML Signature, these two sides should agree with Canonicalization Method, Transform Method, Digest Method, and Signature Method before they start communication.
Mandatory methods defined in  should be supported by IRPManager and IRPAgent.
When an XML document instance is to be exchanged over Itf-N, the sender should make sure the whole XML document instance should be signed. The corresponding XML Signature should be held in the XML document instance.
When an XML document instance is received, the receiver should verify the XML document instance by using the process defined in .
If the verification is successful, receiver works with the XML document instance as normal; otherwise receiver should raise a security alarm if it is IRPAgent or process the failure in a vendor specific way if it is IRPManager.
