46  * PeerValidator validates the peer in an AXIComponent.
47  * It is possible that the code generator, sets arbitrary peer values
48  * for various AXIComponent. AXI sync should treat those components as
49  * invalid. For example if there was an ElementImpl but the peer was found
50  * as an ElementReference then that ElementImpl is bad.
