I think that if you like the idea of profiles it is worth at least adding use cases to that issue
so that we can find out if simple spec language will be good enough or not. If there is to
be a general mechanism by which clients can find out what type of resource they can 
POST to a container that has profile restrictions then simple spec language won't do. On the other hand it may not be as difficult as it seems: it may already have been defined somewhere in the W3C or on the web, it may be just a matter of defining a few relations,
it may be that a WG or Community group can do that while this group is progressing. It may be that these restrictions are not needed at all.

Whatever: putting forward use cases for Issue-48 will be the only way to tell.
