21 * Implementation note:
23 * This implementation assumes Binding V1 semantics for actions, which means actions are packaged along with RPCs
24 * into a single interface. This has interesting implications on working with RpcServiceMetadata, which only
25 * handles the RPC side of the contract.
27 * Further interesting interactions stem from the fact that in DOM world each action is a separate entity, so the
28 * interface contract can let some actions to be invoked, while failing for others. This is a shortcoming of the
29 * Binding Specification and will be addressed in Binding V2 -- where each action is its own interface.
