Package causets (TikZ based)

[c-minz]

Thanks for the nice work.
I'm the maintainer of the LaTeX package causets, which is based on TikZ. I have been asked for support with the experimental feature on arXiv to convert papers to HTML using LaTeXML when using the causets package. As instructed in the Wiki, I have tested it with the option --includestyles on my end but I encountered errors, which I could only partially resolve.

The package version v1.5 (in development) is available at the repository https://github.com/c-minz/LaTeX-causets. It includes:

• a new version of the style file causets.sty that solves some issues with LaTeXML, and a new keyword attribute alt={...} to provide an alternative text for HTML (which is not yet supported by the base package tikz to my knowledge)
• a new file test_causets.tex to test main features of the package
• its pdflatex compiled output as test_causets.pdf and
• its latexmlc compiled output as test_causets.html currently with errors
• the issue tracker Compatibility with ArXiv c-minz/LaTeX-causets#3 for the LaTeX package

Any of the main macros of the package sets up a number of nodes called (E#) where # is a dynamically assigned integer. Since these shape names are dynamically composed (in line 336 \node[causets/.cd, #1] (E\causet@E@i) of causets.sty), LaTeXML seems to have trouble to pick up these names and thus causes a sequence of errors. My log file is below.

The version 1.5 of the causets package is left "in development" so that I can modify the package before sending it to CTAN again. Let me know if there is some part that I could implement in the package to resolve the conversion errors, or if I can add further support with the alt keyword feature.
