This is the text I was referring to An implementation may be able to recover from some errors in a sequence of bytes that is almost, but not entirely a well-formed encoded CBOR data item. -----Original Message----- From: CBOR <cbor-bounces@ietf.org> On Behalf Of Felipe Gasper Sent: Sunday, June 30, 2019 2:56 PM To: Jim Schaad <ietf@augustcellars.com> Cc: draft-bormann-cbor-sequence@ietf.org; cbor@ietf.org; Carsten Bormann <cabo@tzi.org> Subject: Re: [Cbor] Review of draft-bormann-cbor-sequence What is the advantage of defining a CBOR data sequence as a simple concatenation versus a tagged CBOR array of indefinite length?
