From 2b4c8854bfb1034983a228ba6ba098c0f5320d2e Mon Sep 17 00:00:00 2001 From: Stanislaw Baranski Date: Thu, 23 Feb 2023 19:27:00 +0100 Subject: Add the vertical bar qualifier explanation The vertical bar qualifier explanation is missing, but it's widely used interchangeably with the colon qualifier.
