Notational Conventions
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and "OPTIONAL" are to be interpreted as described in RFC 2119.
The key words "unspecified", "undefined", and "implementation-defined" are to be interpreted as described in the rationale for the C99 standard.
An implementation IS compliant if it satisfies all the MUST, REQUIRED, and SHALL requirements.
An implementation IS NOT compliant if it fails to satisfy one or more of the MUST, REQUIRED, or SHALL requirements.
Document Naming Conventions
- The CNAB Core specification is contained in the 1xx documents.
- The CNAB Registry specification is contained in the 2xx documents.
- The CNAB Security specification reserves 3xx level documents.
- The Claims specification reserves 4xx documents.
- The CNAB Dependencies specification uses 5xx documents.
- The 8xx-level documents are reserved for non-normative guidance.
- The 9xx-level documents are reserved for process documents.
The top-level description of each specification is found in the x00 sections (e.g. 100 is the top of the CNAB Core specification, while 200 is the top of the CNAB Registry specification). Specifications may be broken down into subsections, which are numbered incrementally according to their section. Thus, the CNAB Core specification has a 100 (top-level) with four subsections (101, 102, 103, and 104). The 8XX section is entirely composed of non-normative documents, and each 8XX document stands alone.
