a related "native first" project

Hi everybody.
I'm an individual and I recently created a W3C account to post a related
"native first" project.
https://www.w3.org/community/blog/2023/03/07/proposed-group-declarative-dynamic-extensions-to-html-community-group/

This is a set of html extensions that aims to reduce javascript requirement
and perform a lot of dynamic behaviours in a declarative way.

This project aims to extend the html separation of concerns by adding a
layer between styles and the html page itself feeding the shadow dom inner
content of xml / html elements. The goal is to provide a declarative way
(without javascript requirement) to design shadow dom of elements using a
set of templates given in an external sheet ressource (like CSS : it's
called XML Design System Sheet)

As a result, JS framework and CSS framework requirements are decreased in
many cases.
Then, you may be interested in it.

For now I'm totally alone on this project, and I will greatly appreciate
feedback.

Finally, I will be happy if there are some supporters to this newly
proposed community group.
Thank you,
Flavien.
