+// While the Netscape certificate type extension is not a standard and has been
+// discouraged from use for quite some time, it is still encountered. Thus, we
+// handle it slightly differently from other unknown extensions.
+// If it is not marked critical, we ignore it.
+// If it is marked critical:
+//   If the basic constraints and extended key usage extensions are also
+//   present, we ignore it, because they are standardized and should convey the
+//   same information.
+//   Otherwise, we reject it with an error indicating an unknown critical
+//   extension.
