I don't know why it is tied to certain types.

Surely it is a syntactic property of an argument of a subprogram. It 
must be user-defined.

There is nothing here specific for tagged types, except that for a 
primitive operation all its instances could share the property if the 
argument is controlling, which again, is merely a convenience rule.

P.S. if Ada had record type interface, member operations would be a part 
of the interface. No magic needed.
