A description is incomplete. It should mention:

These patterns are not competing, but complementing each other. To achieve availability, one needs both fail-over and replication.

"There are two main patterns to support high availability: fail-over and replication. "

Each bridge support some but not all parameters defined in the core (see BridgeParams). Which are supported is announced by the result of ValidParams().
