Ralf Handl commented on ODATA-872:
----------------------------------

As we moved away from a JSON-Schema-based CSDL this issue seems to be obsolete.

> Bound functions and actions appear in json payloads as properties that start with "#" and may contain target, url, etc.  These are not advertised as properties in JSON Schema, because such bound actions/functions can be "externally defined". This is okay because we specify additonalproperties=true, but we lack validation that the contents of a bound function or action is valid. Also, we prevent a service that knows it will never return additional properties from publishing that fact.
> We could use patternproperties to enforce that the value of a property that starts with "#" is a valid payload for a function or action.
> There is concern that adding this pattern property everywhere a bound function/action could appear might be heavy weight.  
> I would like to at least define the shape for an action/function, so that services that want to advertise actions/functions (either through pattern properties or by explicitly advertising actions/functions) can do so.
