There appears to be a typo in this table about parameter serialization...

[InfoSec812]

OpenAPI-Specification/versions/3.1.0.md

Line 1081 in 36a3a67

label | true | . | .blue | .blue.black.brown | .R=100.G=200.B=150

In the current 3.1 OpenAPI Specification the table in the image below seems to have an error which is in conflict with the docs on the OpenAPI web site. I am looking for clarification on this difference. Please see the in-line screenshots for highlighted differences:

Both label notations use dots in this document, but on the web site:

The exploded version uses dots and the non-exploded version uses commas in accordance with RFC6570.

Could someone please clarify and confirm? If this is a mistake, I would be happy to submit a PR to resolve.

If there is no explode modifier, expansion consists of appending a comma-separated concatenation of each (name, value) pair that has a defined value. If there is an explode modifier, expansion consists of appending each pair that has a defined value as either "name=value" or, ...

Thanks all for the extremely quick response and resolution!

I think this is also present in 3.0.3 so I am tagging this for 3.0.4 as well.
