Douglas Woodall in a December 1994 paper defined  "Anonymity" thus:

"The result should depend only on the number of ballots of each possible 
type in the profile
(and not, for example, on the order in which they are cast, or on 
extraneous information such
as the heights of  the candidates)."

(Elswhere in the paper he explains that a "profile" is "a set of 
preference listings, such as might
represent the ballots cast in an election".)

So this version is broader, except that your first sentence is missing.
Regarding that, someone once suggested that a Range election could be 
held with different voters
having different numbers of slots available to them.

In the same paper he gives this definition of  "Neutrality":

"If  some permutation is applied to the names of  all the candidates on 
all the ballots in the profile,
then the same permutation should be applied to the result.  ...
One consequence of  Neutrality is that a tie in a single-seat election 
cannot be resolved simply by
electing the first in alphabetical order among the tied candidates".
