Then let me understand the IMHO fundamental issue about sockets, using the
RFC8610 3.9 tcp-header example:
Lets say i define:
tcp-header-structure [ tcp-header ]
And i have not defined any $$tcp-option
When an implementation of this now receives a CBOR array with not only
2 elements (seq, ack), but with more elements:
MUST it recognize this as a tcp-header-structure - according to CBOR parsing
rules ?
(the way i read rfc8610, the answer is no)
MUST it ignore the array elements after ack ?
