Hi dev,
I would like to introduce class property entity type and related
reference and syntax separator.
For the separator syntax I propose to use the same thing as object
separator since you can't have both in the same reference and it's
always a pain to find a new separator.
FYI it means wiki:space.page^property

Currently there can be only one class in a document, but for a while the
question whether this is going to be valid in the future as well has
been floating around.
So, a prerequisite vote is:
In the new model, can a document contain more than one class?
One thing I believe we're definitely going to need is a special data
structure to explicitly represent XClasses, holding XClass metadata such
as "is the class supposed to be stand-alone, one instance per document,
like BlogPosts, or is it an aggregated class, with several instances
attached to a document, like the Comments"; "what is the sheet used to
display the object in view mode"; "what is the parent class (if we want
to do inheritance)". With this meta-class in place, we could, in theory,
have two meta-classes in a document, with each class property mapped to
one of the meta-classes.

+1, if we decide that we only want at most one class per document.
