 As part of this work, the Working Group may extend PKIX (RFC 5280), e.g. with new extensions or signature algorithms. As appropriate, the PLANTS Working Group will liaise with the LAMPS Working Group to ensure adequate lighting for this work and help it grow. As needed, the Working Group may also define extensions to ACME and TLS to integrate its certificate constructions. In doing so, it is expected to liaise with the TLS and ACME Working Groups for cross-pollination.
