[Fix] 0039485 UI: Escape HTML tag names in Standard Page accessibilit…

[fhelfer]

Error Bad character “ ” after “<”. Probable cause: Unescaped “<”. Try escaping it as “<”.
https://mantis.ilias.de/view.php?id=39485

Replace < main >, < header >, < footer > with <main>, <header>,
<footer> in the docblock so the Kitchen Sink documentation renders
valid HTML (no "Bad character after <" validator errors).

Problem

• In der System-Style-Dokumentation (Standard Page, Accessibility) führten die Docblock-Texte "the HTML tag < main >", "< header >", "< footer >" zu Validator-Fehlern: "Bad character ' ' after '<'".

Lösung

• Im Docblock der standard()-Methode in Layout/Page/Factory.php die Tag-Namen als Entities schreiben: <main>, <header>, <footer>.
• Beim Anzeigen der Doku wird daraus korrekt <main> etc. gerendert, ohne ungültiges Markup.
• Nach dem Merge: Artifact ggf. neu bauen (build-artifacts), damit die Doku aktuell ist.

Hello together,
Thank you very much for your contribution, @fhelfer. Thanks you for your review, @Annett7811. I agree and don't see these issues anymore.
I'm forwarding this to @thibsy for code review. He may contact you with change requests or incorporate the changes directly (That includes cherry picking too.)

Kind regards,

Hi @fhelfer,

Thx a lot for your contribution to the UI framework!

I am not convinced that this is the appropriate solution here. This will be immediately forgotten and the next UI component description might feature characters that need escaping again.

Please implement the following changes:

• Escaping location: please either try to find an appropriate location inside the ILIAS\UI\Implementation\Crawler namespace or the ilKSDocumentation* GUI classes, to properly escape future characters as well.

Kind regards,
@thibsy (as UI coordinator)
