+// if another alternative implementation is created. This package is
+// code-generated and subject to the same license as the go-fed tool used to
+// generate it.
+//
+// This package is independent of other types' and properties' implementations
+// by having a Manager injected into it to act as a factory for the concrete
+// implementations. The implementations have been generated into their own
+// separate subpackages for each vocabulary.
