Description

We skip over booleans in our description of ANS.1's basic types, in our table of tag values, and in our description of DER serialization. This seems like an odd omission, given that they're commonly used in x509 (e.g. for the Critical field on extensions) and that DER places interesting restrictions on how they're encoded. Let's add a brief treatment of bools to this doc.

Research direction

Find the document titled “A Warm Welcome to ASN.1 and DER” and read its sections on basic types, tag values, and DER serialization. Done means those three areas briefly cover BOOLEAN values, including their relevance to X.509 and DER’s encoding restrictions.
