To the extent that the type is implicit in the protocol, e.g. SRM = file, you don't necessarily need an extra attribute at all, and you also have the Capability attribute for things which are relatively generic - we already have data.access.flatfiles for example. Also in the Share we have an AccessMode attribute - for which I think we don't actually have a use at the moment!
