pointless (at least for us, services are pretty deterministic and skipping straight to attribute request makes a lot of sense).
To make up for giving up the service request provide url list, track and fill in srvtype when the reply comes back so that caller knows which data elements match which of the requested service types.

TODO includes IPv4 SLP and reworked multi-srvtype support since RFC indicated behavior doesn't work (divide multiple srvtypes into separate packets to workaround)
