Re: Web Access Control - Authorization condition with capability detection

Thank you Sarven!

Would you like to bring it up during a CG call?

I would like to suggest next week, since Christoph should be available again.
https://www.w3.org/events/meetings/9d3965a2-f4a0-4346-8ca6-8eadee10051c/20260401T140000/

As I mentioned many times my implementation relies on client constraints so it is a very important feature to me.
Currently registry pods are using ACP as in https://github.com/solid/authorization-panel/blob/main/proposals/evaluation/uc-2.5.2-client-constraints.md

Please let us know whenever, and if, you would like to put it on CG meeting agenda.

Best regards,
elf Pavlik
