The pre-Maastricht proposal was to limit to zero or one locationValue, but that blew up Richard's rough-loc ID (which defines a coarse location for routing, and accurate location for endsystems). This is why we made the compromise of allowing a second locationValue. If we allow 'many', we need to bloat the doc with all that "inserter=" and "inserted-by" crud, and we don't want that, do we? james >This is confusing for computer scientists who can only count: zero, >one, many.) > >--Martin
