      Rephrase the definition of such functions:

      Service-defined bound functions that take an entity set as their binding parameter MAY be used as set transformations within $apply if the type of the ...

      New:

      Description

      The current text in 3        System Query Option $apply makes an incomplete statement about the return type of such a function in a sequence of $apply transformations: “If it returns an entity set, further transformations can follow the bound function.” This leaves room to use also functions that return a value of a complex or primitive type, which does not fit to the general principle of “set in/set out” for all transformations and the result of $apply being a collection of instances.
