This warning has been in tex4ht for long time. Finally I am able to make MWE
to reproduce it.
This is a book class, with two parts. When one part does \subimport{.}{B} to
load B.tex which is book class document which has \chapter in it, tex4ht
generates this at the end of B.tex when compiled
--------------------
l.13 — TeX4ht warning — \SaveEverypar’s: 2 at \begindocument and 3
\enddocument —
------------------------
Here is MWE and command used. I am using TL 2025 updated today. This is A.tex
file
---------------------------
\documentclass[12pt]{book}%
\usepackage{standalone}
\usepackage{import}
\setcounter{secnumdepth}{6} %for body of book to show subsubsubsection
\begin{document}
\title{my book title}
\author{me}
\date{\today}
\maketitle
\ifdefined\HCode
\Configure{tableofcontents*}{part}
\TocAt{part,chapter}
\TocAt{chapter,section}
\else
\setcounter{tocdepth}{0}
\tableofcontents
\fi
\part{Introduction and design}
\chapter{Introduction}
\section{Supported differential equations}
text...
\section{Types of solutions supported}
text...
\chapter{Design of the ode solver program}
text...
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\part{First order ode $F\left( x,y,y^{\prime}\right) =0$}
\subimport{.}{B}
\end{document}
--------------------
And this is B.tex in same folder as A.tex
--------------------------
\documentclass{book}%
%\usepackage{standalone} %has no effect
%\standalonetrue %has no effect
\begin{document}
\chapter{Existence, uniqueness}%
to do
%WARNING SHOW HERE
\end{document}
---------------------
The command used is
make4ht -ulm default -a debug A.tex 'mathjax,htm,6'
The split level 6 above does not matter. I tried 2,3,4,5 and they all produce
same warning.
enter image description here
The output of the command produces these warnings

This zip file
https://12000.org/tmp/070325/tex4ht_warning.zip
contains everything in one folder, including the log file, HTML produces and
.tex files
enter image description here
Am I doing wrong? Why tex4ht generates these warnings? And what to do so they
do not show?
Note: lualatex compiles A.tex with no warnings or any issues.
