<http://greenbytes.de/tech/webdav/rfc2518.html#rfc.section.4.1>:

"Properties are pieces of data that describe the state of a resource. 
Properties are data about data."

Also note that aforementioned live property wouldn't *vary* by binding; 
it would just be random. What I'm looking for is a use-case where 
properties varying by *binding* really make sense. So far, I'm not aware 
of any case where this wouldn't be better modelled as a property on the 
collection holding the binding.

I tend to disagree here (judging from previous reactions) :-)
