The template class describes an object that can serve as a locale facet, to characterize various properties of a message
catalog that can supply messages represented as sequences of elements of type E
.
As with any locale facet, the static object id
has an initial stored value of zero. The first attempt to access its stored
value stores a unique positive value in id
.
