If that's a fallacy, is this article also a fallacy?
Actually, I'm not sure SMIL is used widely in signage industry,
because SMIL isn't used for signage at all in Japan (where I live in).

Although I'm not sure if SMIL is used widely or not,
it's true that SMIL is used in signage industry and
there are signage operators who want to enhance SMIL.

The doc reflects the statements for the workshop held at Japan in June this year.

Me too.

"A declarative approach" mentioned in the doc doesn't mean
creating new languages nor changing existing languages.

If Google docs is a good solution for creating contents for signage,
why isn't it used in signage industry?

For signage? I didn't know that.
Could you show us some actual cases in which Google docs are used
for signage contents?

You misunderstand me.
I don't back up SMIL.
In the doc, it is simply listed as a possibility.

The doc isn't a specification nor a standard.
It's just a material for further discussion.
The doc doesn't determine using SMIL for Web-based Signage.

You are right.

I know what is Web.
If you want to do so, you can do it.
No one deny it.
"Web-based Signage" is achieved by only web technologies.
So it's naturally able to be viewed everywhere technically.
