+// Tests the interaction between the basic constraints extension and the
+// certificate version field. In general, the testcases consist of verifying
+// certificate chains of the form:
+//
+// end-entity (issued by) intermediate (issued by) trusted X509v3 root
+//
+// where the intermediate is one of X509 v1, v2, v3, or v4, and either does or
+// does not have the basic constraints extension. If it has the extension, it
+// either does or does not specify that it is a CA.
+//
+// To test cases where the trust anchor has a different version and/or does or
+// does not have the basic constraint extension, there are testcases where the
+// intermediate is trusted as an anchor and the verification is repeated.
+// (Loading a certificate with trust "CTu,," means that it is a trust anchor
+// for SSL. Loading a certificate with trust ",," means that it inherits its
+// trust.)
+//
+// There are also testcases for end-entities issued by a trusted X509v3 root
+// where the end-entities similarly cover the range of versions and basic
+// constraint extensions.
+//
+// Finally, there are testcases for self-signed certificates that, again, cover
+// the range of versions and basic constraint extensions.
