In v3.6 we further detailed the definition of the ENUM VARIABILITY in #683 . As a result we kept the definition:
// Sign that can change semantically and/or positionally, i.e. it is
// left unspecified in which way the sign may change.
//
// \note This value represents a legacy definition. If possible, please
// use the more specific values below to indicate the exact nature of
// variability.
//
VARIABILITY_VARIABLE = 3;
It is to be discussed if this is already covered by VARIABILITY_OTHER and if the value above can be omitted in a major version change.
