RE: Updated invitation with note: MathML Refresh Meeting

Hello,
 
I have been asked to carry a message concerning Chemistry. I am told that MathML supports Chemistry notation, at least some. However, Assistive Technology cannot determine semantically when it is Math or Chemistry.
 
I know this dips into content versus presentation, but perhaps a bucket for Chemistry could be identified.
 
Best
George

Whatwg-flavoured html is a "living document" with rolling updates and no 
version number, w3c-flavoured html is versioned (currently at 5.2)
I don't think it's any secret that there is a certain amount of tension
behind HTML being published by two organisations with two versioning 
strategies.
We just need to fit in with both in the least disruptive way possible...
OK, I guess we should follow W3C's versioning rules if the plan is to release as a W3C spec in the future. IIUC, browser implementers generally just rely on the Working Draft versions.
Also, for WhatWG the HTML editors are pretty liberal about pointing to the current best spec. So I think we could have https://html.spec.whatwg.org/#mathml pointing to MathML Core draft once we have a stable URL on our side and the draft is a bit more advanced. We'd want 2/3 browsers to sign off on this reference though.
