Here is a "new" proposal: * introduce now class property references with "wiki:space.page^property" in which we escape "^" and "." when serializing the "property" * that way if later we really need to have several classes by document (which does not actually bring anything I agree with Denis) we support wiki:space.page^property as a shortcut of wiki:space.page^firstclass.property. It would be a first but it's not hard to do technically. If we don't for sure we can always remove the "." escaping which is just a useless escaping which is supported properly by reference parser and otherwise we don't really break the syntax by adding the classname part to the reference since the separator is already protected.
WDYT ? I really need to move on on this and I'm -1 to introduce right now a wiki:space.page^classname.property syntax where you never know what to put as classname.
