Artifact tags break when working across different InDesign UI languages

For example, “Außertextliches Element” (German) only exports correctly from a German InDesign. Exporting the same tagged file from an English InDesign makes the artifacts visible in PAC, even though other tags (H1, H2, etc.) work consistently across all language versions.

Steps to reproduce:

1. In InDesign with the UI set to English, tag an element as Artifact.
   → Exports correctly, artifact is hidden in PAC.
2. In the German version of InDesign, the equivalent tag is “Außertextliches Element.”
3. Apply this German tag, then export the PDF from the English version of InDesign.
4. Check the PDF with PAC → the artifact becomes visible.

Observed behavior:

• When artifact tags are applied in German but exported from English InDesign, the elements are visible in PAC instead of hidden.
• Artifact tags behave inconsistently between language versions.

Expected behavior:

• Artifact tagging should behave consistently across all InDesign UI languages, the same way structural tags (H1, H2, H3, etc.) already do.
• The UI language should not affect accessibility compliance in exported PDFs.

Impact:

• Our publishing team works across multiple languages (German, English, Spanish, and French).
• Some colleagues cannot set their UI to German but still need to produce compliant German-language PDFs.
• This inconsistency causes avoidable accessibility errors and slows down production workflows.
