+# To validate A, there are several possible paths, using A(B) to indicate
+# the certificate A signed by B:
+#
+# 1. A(B) -> B(C) -> C(D) -> D(D)
+# 3. A(B) -> B(C) -> C(E) -> E(E)
+# 4. A(B) -> B(F) -> F(E) -> E(E)
+#
+# That is, there are two different versions of C (signed by D and E) and
+# two versions of B (signed by C and F). Possible trust anchors are D and E,
+# which are bth self-signed.

[davidben, 2016/01/28 20:52:32]

Nit: bth -> both

+#
+# The goal is to ensure that, regardless of the revocation status of C or F,
+# clients are able to successfully build a valid path.

[davidben, 2016/01/28 20:52:32]

Nit: "regardless of the revocation status of C or F" probably should be "as long
as at least one of C or F is still valid" perhaps?
