The wrong (by W3C) head hreflang="gsw-berne" HTML tag:
<link rel="alternate" hreflang="gsw-berne" href="https://www.domainXXX.com/ch/ihr-spezialist-fur-abdichtungen-und-markierungen" />
which is reported by W3C as an error (attached screenshot):
Error: Bad value gsw-berne for attribute hreflang on element link: Bad variant subtag berne.
From line 22, column 1; to line 22, column 128
<link rel="alternate" hreflang="gsw-berne" href="https://www.domainXXX.com/ch/ihr-spezialist-fur-abdichtungen-und-markierungen" />↩<link
There are two variants for the issue fix:
1. Patch the core language version #3 🐛 Replace 'gsw-berne' (Swiss German language) with 'gsw' (W3C compliant) Needs work . For new projects.
2. Modify the output only ( #9 🐛 Replace 'gsw-berne' (Swiss German language) with 'gsw' (W3C compliant) Needs work ). More suitable for existing (old) projects.
Both of the patches replace core language hreflang="gsw-berne" (German Swiss language) with hreflang="gsw" (W3C compliant).
