Summary

Formal syntax on CSS sizing propertywidth,max-width,min-width etc. pages do not accumulate values from all the specs.

Reproduction steps

1. Open pagehttps://developer.mozilla.org/en-US/docs/Web/CSS/width#formal_syntax
2. Observe the Formal Syntax section
3. Then observe BCD table at the bottom
4. The BCD table lists values likestretch andanchor-size() which are not there in the Formal Syntax.

Expected behavior

In sizing properties cases, the formal syntaxes should accumulate value syntaxes from all the spec webref jsons:

• css-sizing
• css-sizing-4
• css-anchor-position-1

Also, in the case of all other feature syntaxes, accumulate value syntaxes from all the available specs jsons.

Actual behavior

The Formal Syntax section shows only the syntax fromcss-sizing.json.

Anything else?

I've raisedan issue in Webref to map sizing properties to theanchor-size() value.
