Do not assume that just because it is a m file that it will work in any
version.  It will not.  Correct behaviour for that function is dependent
on changes made to isa() 3 days before [1].  This is mentioned on that
bug report [2]:

I do not know if it is dependent on any other change also made on the
default change so mix files from different development branches at your
own risk.

Also, the way I see it, validateattributes() is most useful for users who are
developing code for others.  It is probably not a good idea to write code
for others that is dependent on unreleased versions of Octave.
