      It would be nice if you could do this:

      for (ModelNode ref : PROXIES.resolveModelAttribute(context, model).asListOrEmpty()) {
    String asString = ref.asString();
    this.outboundSocketBindings.add(new InjectedValueDependency<>(CommonUnaryRequirement.OUTBOUND_SOCKET_BINDING.getServiceName(context, asString), OutboundSocketBinding.class));
}

      instead of this:

      ModelNode node = PROXIES.resolveModelAttribute(context, model);
if (node.isDefined()) for (ModelNode ref : node.asList()) {
    String asString = ref.asString();
    this.outboundSocketBindings.add(new InjectedValueDependency<>(CommonUnaryRequirement.OUTBOUND_SOCKET_BINDING.getServiceName(context, asString), OutboundSocketBinding.class));
}

      The asListOrEmpty method would return a Collections.emptyList() if the value is undefined, similarly to the existing asStringOrNull and related methods.
