Status: Held for Document Update
Type: Technical

Reported by: Corey Bonnell <[email protected]>
Date Reported: 2022-02-16
Held by: John Scudder (IESG)

Section: 4.8.1

Original Text
-------------
  The Basic Constraints extension field is a critical extension in the
  resource certificate profile, and MUST be present when the subject is
  a CA, and MUST NOT be present otherwise.

  The issuer determines whether the "cA" boolean is set.

Corrected Text
--------------
   The Basic Constraints extension field is critical and MUST be present 
   when the "cA" field is TRUE, otherwise it MUST NOT be present.

Notes
-----
See discussion at 
https://mailarchive.ietf.org/arch/msg/sidrops/dPCiDz_pDR68G4cTC8W7X5LTE5o/

The original text is tautological -- Since according to RFC 5280 ยง4.2.1.9 the 
"cA" boolean MUST be set when the subject is a CA, and MUST NOT be set when the 
subject is not a CA, then it's axiomatic that 

cA boolean set <=> Basic Constraints field present <=> subject is a CA

Although the original text is not strictly speaking wrong, it's potentially 
misleading since it could be read as implying that it's possible to have the cA 
boolean FALSE in a CA certificate, which is not so.
