Great, so basically the attribute interfaces could be merged on the
sending side.

I think I can live with checking for the bit on the receiving side,
the only problem it could cause is when the attribute type is used
to encode information such as a port number. So if we are willing
to take that risk the receiving path could be merged as well.
