[tex4ht] [bug #477] Support for new LaTeX hook management

[Michal Hoftich]

Hello Ulrike,

> Which fatal clash?  Do you have an example?

Sorry, it is not a fatal crash, only a bunch of error messages and
invalid generated HTML file. I think I've posted this sample before,
but here it is to be sure:

%%%%%%%%%%%%%%%%%%%%
\DocumentMetadata{testphase={phase-III,math}}
\documentclass{article}
\usepackage{graphicx}
\usepackage{amsmath}
\begin{document}
\section{Does section work?}

hello inline $a = b$.

\[
  a = \frac{b^2}{\sqrt{c}}
\]

\end{document}
%%%%%%%%%%%%%%%%%

You can compile it using:

$ make4ht -m draft -a debug sample.tex "mathml"

Without display math, it compiles without problems, so tagging doesn't
cause errors on itself, but only when you use commands that clash.

Best regards,
Michal
