<p class="MsoNormal" style="margin-left:.5in">One other concern that I have, but I am not sure how to properly address it, so I want to just throw it out: I think we will have to have some option for versioning sets - only this will prevent a blow up in sets
that we have to remember once we go to dynamic sets. In this case, an MPI implementation would only have to report data for the latest set and hence could replace sets. I know we don’t want to deal with this now and we are also not sure, if this is the right
answer, but it would be nice to add something that allow us to do this later. Adding a real version argument is probably too vague at the moment, but what about adding a - currently unused - info object in the PSET query function? Another option would be to
reserve a character in the URI that right now can’t be used, but later can be used as a delimiter. <o:p></o:p></p>
