Here I'm not suggesting to remove the support for anonymous endpoints. My
suggestion was to force a name to every endpoint regardless of weather they
are defined in-line or separately.

Even now user can do this. But system doesn't enforce this, and we have
to generate a name. So my suggestion was to make the name attribute of
the endpoint mandatory.

Thanks,
Supun..
