+// Form defines a plural form.
+//
+// Not all languages support all forms. Also, the meaning of each form varies
+// per language. It is important to note that the name of a form does not
+// necessarily correspond one-to-one with the set of numbers. For instance,
+// for Croation, One matches not only 1, but also 11, 21, etc.
+//
+// Each language must at least support the form "other".
