ACAL Core - Invalid references to URI spec (RFC 2396)

[cdanger]

1. There are still references to obsolete RFC 2396 on URI, in sections C.2.3 IP address, C.2.4 DNS Name, 7.1.2.3.8 IdentifierType and 8.3 Identifier Evaluation. Whereas 7.1.2.3.1 URI, 7.1.2.3.7 ShortIdValueType, 7.3 ShortIdType refer to the newer RFC 3986 as they should. All should refer to RFC 3986.

2. RFC 3986 is missing in References section.

3. C.2.3 IP address says:

   the address and mask are formatted in accordance with the syntax for a "host" in IETF RFC 2396

   However, the mask is not defined in RFC 2396 or 3986. Is this in another RFC?

[cdanger]

I've replaced RFC2396 with RFC 3986 in section B.1 References, and fixed the reference in 7.1.2.3.8 IdentifierType, and 8.3 Identifier Evaluation. See 1710d94.
But C.2.3 IP address and C.2.4 DNS Name still need to be fixed.
