Browsers indeed have already implemented some support for top-down writing. But as it is with right-to-left languages, browsers only provide some infrastructure, and the web developers have to actually use it. For RTL in MediaWiki it's CSSJanus and a lot of little tweaks all over the place. For SignWriting I haven't looked into details yet, but I suppose that it's comparable.

Hi,

Is not top/down and the various related things currently proposed by W3C
mainly a task to be undertaken by browser makers? Should we not wait for
the first updates to appear?

Hoi,
The interface of MediaWiki is right to left or left to right. With ASL
it has to be top down. This is something that has never been
considered. I have asked for ASL to become a full project so that the
issues can be properly seen, diagnosed and remedied. It will be
supported by the SignWriting Foundation. There is no chance that it
will be abandoned and it is imho enough reason to allow for it to be
created at this time.
Thanks,

The language policy allows us to be flexible with how we interpret

I made several proposals over te last few years and they have all
been torpedoed.

Which ones?

ASL is the latest example of this. It makes sense to allow for one

Wikipedia with SignWriting because it is the only way that we will
get the technical aspects of MediaWiki right. It means that issues
will be exposed in Commons and Wikidata as well.

Can you explain why the incubator isn’t enough? I mean, if it’s
not working entirely well, isn’t that a problem?
