3 Issues when using XyJax-v3 and Lwarp for typesetting xymatrix diagrams

Please do contact me if you know the solution to any of these issues. Remember: this is stricly a non-specialist file!

• The commands of the form:
```
\stackrel{(*)}{\implies}
```
or
```
\left ( x \xrightarrow{f} y\right)
```
do not seem to work well inside
```
\begin{equation} \end{equation}.
```
So use instead, for example,
```
$$ \stackrel{(*)}{\implies} $$
```
```
$$ \left ( x \xrightarrow{f} y \right)$$
```
Here is how it looks:

\[ \stackrel {(*)}{\implies }\]

\[\left ( x \xrightarrow {f} y \right ) .\]
• Sometimes there are errors if there are mathematical commands in the title of sections, subsections, etc.
• Lwarpmk gives error messages if it finds xymatrix inside:
```
\begin{equation} \end{equation}.
```
(However a html file can still be produced with lwarpmk pdftohtml.)

So avoid:
```
\begin{equation} \xymatrix{   } \end{equation},
```
and use instead:
```
\[ \xymatrix{   } \],
```
or
```
$$ \xymatrix{   } $$.
```
• Not all accessibility functions of MathJax work with Xy-Jaxv3, only some can be used, e.g. zoom and source latex code.
Accessibility features of Xy-jax are not officially supported.
• References to section, chapters etc, have glitches if inside mathematics environments. For instance, the links provided do not appear to work well. E.g.
$\seteqnumber{0}{}{1}$
\begin{equation} \label {Euler} \exp (x+yi)=e^x\big (\cos (y)+i\sin (y) \big ) \end{equation}
$\seteqnumber{0}{}{2}$
\begin{align*} e^{i\pi }+1&=\big (\cos (\pi )+i\sin (\pi ) \big )+1, \quad \textrm { using Equation } \eqref {Euler}. \textrm { (Just for testing) equations } \eqref {test}, \eqref {xydiagram}\\ &=0. \quad \textrm { A reference to second section } \protect \ref {sec:context} \end{align*} Outside maths environments all seems to work fine:

Using Equation (2). (Just for testing) equations (1), (3)

• When compiling xymatrix, or tikz, diagrams as sgv figures, with Alt-Text (which sometimes is necessary) it sometimes happens that the figure is not cropped correctly. This seems to depend stronly on the operating system being used.
