I looked into jsMath and I actually like it. I'd wish browsers would
WHATWG could add just one tag:
<math type="mime/type" src="file">
That would work much like script does, or ... browsers could use the
advantages of <object>. I believe the latter would be best suited, since
it provides fallback capabilities.
As you said, as James said, and as far as I know, LaTeX is the most used
language for mathematical scientific documents.
The fact the content in the <object> (the mathematical formulas) can't be
styled via CSS, nor modified via JS+DOM, is by far a lesser problem than
not having any support at all for any mathematical language.
If jsMath can achieve nice results via DOM manipulation for rendering
LaTeX code, why wouldn't be a browser capable of doing that? It should
actually be even more powerful, faster and capable of implementing even
what the guy wasn't able to.

The rendering George achieved is not that bad, and certainly it's not

I have to agree with Juan on this. The fact those scientific documents are
rendered properly in about 2% of UAs (by number of users) is not a problem
at all, since it all relies on the CSS implementation in the other UAs.
This problem is bound to be solved in future releases of any UA. As Juan
said: Firefox will have a fix. Internet Explorer is an atypicial (might I
add a tragical) example, not worth going into details.

Why isn't LaTeX good enough for the web?
If we wouldn't have CSS and someone, today, would come up with a CSS-like
proposal we'd trash it since it's not "good enough"? Please define "good
enough" for the web.
I see LaTeX as was CSS 10 years ago:
- no implementation
- very different syntax (not SGML/XML based)
- no "DOM integration"
But LaTeX has important advantages:
- it is proven to be very good for publishing scientific documents
- it has many open-source implementations
As you can see, I am for reusing existing technologies and formats, not
for adding yet another one.
The guys from Opera Software and Mozilla Corporation could just say "no"
to everybody and just go ahead and implement support for LaTeX as
<object>. That would really make all authors of scientific documents very
Thing is, CSS implementation required big changes and was a different
approach. LaTeX is just like implementing support for a new image format.

I would like to see a specification of CanonML and working examples with
an experimental implementation. Your site provides only talk about
CanonML. Is it too early to ask for this?
If you have some, send it over to my (private email).

Maybe you didn't look into the site careful enough. I was also referring
MathWebSearch is an entire application which deals with indexing Content
MathML and allows users to input Content MathML code as search query.
Therefore, that's not something different. As far as I know, the semantic
search engine can be extended to any XML format (for indexing and for
search query input). The guy actually added support for OpenMath search
queries. More technical details are available in the page.
