[whatwg] Exploring new vocabularies for HTML

I've read all 367 e-mails that were sent to the WHATWG, the HTMLWG, and to
other forums on the topic of MathML, SVG, namespaces, etc, in HTML,
spanning threads from 2006 to 2008. [1]
I've tried to summarise the problems (use cases) that people want solved,
along with what they consider most important when faced with those
problems [2]:
1. Putting an equation in a Web page.
Priorities:
* Maintainability
* Searchability
* Accessibility
* Typographically-sound printing
* Ease of authoring (are authors willing to learn new formats?)
* Ease of import from existing documents
* Ease of implementation (are UAs willing to implement new formats?)
* Resistance to errors (e.g. not brittle in the face of syntax errors)
2. Migrating from LaTeX to HTML.
Priorities:
* Fidelity
3. Writing a document by hand, with inline diagrams imported from a
graphics package.
Priorities:
* Compatibility with existing graphics packages
* Resistance to errors (e.g. not brittle in the face of syntax errors)
* Scriptable (retained-mode, with DOM support, without requiring
cross-frame scripting)
* Round-tripping (the ability to take image fragments from a Web page
and edit them)
4. Writing documents that include diagrams that include
typographically-correct mathematics.
Philip also wrote a detailed story, which touches on several of the points
above, of what we want to enable. In addition to the points above, his
requirements include a solution for ID clashes in multiple-document
transclution, and a solution for embedding custom non-visible data in an
HTML document for scripting purposes. [3]
Now, please, if I've missed something that you want to do, please let me
know as soon as possible. I intend to start working on solutions to these
problems tomorrow, and things that aren't on the list of problems will
likely not be considered as constraints.
In particular, people seemed to jump to solutions that the above problems
don't imply. For example, nowhere in the above list of problems do
namespaces appear anywhere, yet the majority of the discussion revolved
around namespace issues. If this is because I've missed a problem that in
fact requires those solutions, please tell me as soon as possible.
I cannot solve problems I don't know exist!
