+The class locale​::​id provides
+identification of a locale facet interface,
+used as an index for lookup and to encapsulate initialization[.](#1.sentence-1)

+[*Note [1](#note-1)*:
+
+Because facets are used by iostreams,
+potentially while static constructors are running,
+their initialization cannot depend on programmed static initialization[.](#2.sentence-1)
+
+One initialization strategy is for locale to initialize each facet's id member
+the first time an instance of the facet is installed into a locale[.](#2.sentence-2)
+
+This depends only on static storage being zero
+before constructors run ([[basic.start.static]](basic.start.static "6.10.3.2 Static initialization"))[.](#2.sentence-3)
