RFC 9309, "Robots Exclusion Protocol", September 2022

Source of RFC: IETF - NON WORKING GROUP
Area Assignment: art

Section 5.2 says:

In the following case,
/example/page/disallowed.gif MUST be used for the URI
example.com/example/page/disallow.gif.

It should say:

In the following case,
/example/page/disallowed.gif MUST be used for the URI
example.com/example/page/disallowed.gif.

Notes:

The two file names in that sentence ("disallowed.gif" and "disallow.gif")
doesn't match. i.e. "ed" is missing from the second file name.

This error renders the example given in section 5.2 incorrect.

Notes:

The "Path" component of third example seems to indicate Unicode codepoint, rather than UTF-8 encoded hexadecimal. If it was, the correct codepoint for %E3%83%84 is U+30C4, or ツ (in Unicode form).

Section 2.2 says:

path-pattern = "/" *UTF8-char-noctl ; valid URI path pattern

It should say:

path-pattern = ("/" / "*") *UTF8-char-noctl ; valid URI path pattern

Notes:

The `path-pattern` rule requires that `/` be the first character, but the Simple Example in section 5.1 has `Disallow: *.gif$`, where the path pattern starts with a `*`. The notes preceding the example explicitly say: The "*" character designates any character, including the otherwise-required forward slash; see Section 2.2.

This seems to indicate that either the formal syntax is wrong or the guidance in section 5.1 is wrong. I assume the formal syntax is wrong.
