Namespaces: Also Mention ":" as Namespace Delimiter

[gregweb]

I very like the specification proposes to add namespaces.
As followed my proposed minor addition to the spec.

Current

Namespace delimiter examples are "." or "/".

Spec sections:

• "4.6.1. Extension Keys":
  • "SHOULD include a delimiter (e.g. . or /) separating the namespace from the identifier"
  • "The ctrf. and ctrf/ namespace prefixes are reserved for CTRF-defined extensions.
    Producers other than CTRF MUST NOT use extension keys beginning with ctrf. or ctrf/."
• "D.6. CTRF Document with Namespaced Extra Objects"

Proposed change

• under section "4.6.1. Extension Keys" also add ":" to the example delimiters
  • "SHOULD include a delimiter (e.g. . or / or :) separating the namespace from the identifier"
  • "The ctrf., ctrf/ and ctrf: namespace prefixes are reserved for CTRF-defined extensions.
    Producers other than CTRF MUST NOT use extension keys beginning with ctrf., ctrf/ or ctrf:"
• under section "D.6. CTRF Document with Namespaced Extra Objects" add the following or similar:
  To express at top level that a key is namespace key as opposed to a non-namespace key, the namespace delimiter MAY be appended to the namespace key. Example (with : namespace delimiter)

"extra": {
    "myorg.ci:": {     // mind the trailing ":"
        "pipeline": {
        }
    }
}

An Addtional Idea

It may make sense to specify at top level which namespace delimiter is used within the document:

5.10. namespaceDelimiter [or nsDelimiter]

Description:
Identifies the namespace delimiter used in this report.

Requirements:
namespaceDelimiter is OPTIONAL.
If present, it MUST be a non-empty string.
[I initially thought to restrict the string to a length of one.]
