Whereas the IETF model only models IPsec policy necessary to configure an
IPsec device, the DMTF model also models the current state of the IPsec
device (i.e., what SAs are established).  The classes you mention,
SecurityAssocation and IKESecurityAssocation, are used to model the state of
the device.  That is why you are seeing a duplication.
