slightly differently, and have the links target actual *insets*, rather than just
target paragraphs. That'd mean doing a bit of work on TocBackend, etc.
+Math
+ We have a fair bit of math now working via MathML output, but there are still some
+ isues, and not all the insets work. Here are the ones I know still need work:
+ - AMSArray
+ - Array
+ - Big: Not sure if we can actually do anything here. Probably they should
+ just be treated as delimiters.
+ - BoldSymbol: Should be easy.
+ - Box
+ - Cases
+ - Diff: Code exists, but I do not know if it is right.
+ - Font
+ - Binom (in Frac): None of these tags exist in MathML 2.0. We'll
+ just output a fraction with delimiters.
+ - Lefteqn
+ - MBox: Use <mtext>.
+ - Overset: Use <mover>.
+ - Par?
+ - Phantom: There is some support for this in MathML....
+ - Ref: Probably needs to be deferred somehow, which is a hassle, because it
+ means the whole MathML output business needs a new argument.
+ - Size: Unclear if we want to do anything here, though we could. See
+ lib/symbols for the commands supported, of course.
+ - Space: Needs checking.
+ - SpecialChar: Needs checking.
+ - Split
+ - Stackrel: Use <mover>, probably.
+ - Substack: This is a stack of however many cells, all in a smaller style.
+ Probably do something with <mover>, again.
+ - Tabular: This is more or less a text-like table in math. Probably output it
+ as a table, but set the font.
+ - Underset: Use <munder>.
+ - XArrow: Contents above and below an arrow. Use...?
+ - XYMatrix: Not sure how this differs from ordinary ones.
+
+
These insets do not work and are not yet scheduled to work:
InsetExternal: It may be that this won't be too hard, but I don't understand
these so am not sure what to do. For now, it is disabled.
