The `\AtBeginDocument` command is usually used to redefine macros and initialize stuff. This use works. What is the issue in this case is that it includes a text in the document. As tex4ht outputs the HTML header at this moment as well, it happens that the text goes before HTML.

I don't think we can fix that easily, as we want the code usually executed in `\AtBeginDocument` to be executed before any output is written. In this particular case, I would advice to edit the document:

-----------
\documentclass[english]{minimal}
\usepackage[utf8]{inputenc}

\newcommand\outputatbegin[1]{#1}

\makeatletter
\AtBeginDocument{\outputatbegin{\@title}}
\makeatother
\title{Minimal example}
\begin{document}
Test body.
\end{document}
------------

The `\outputbegin` command can then be redefined for tex4ht in a custom config file:

-------------
\Preamble{xhtml}
\renewcommand\outputatbegin[1]{\Configure{@BODY}{#1}}
\begin{document}
\EndPreamble
-------------

The redefinition uses the `\Configure{@BODY}` command that will output the text after the `<body>` tag.

htlatex produces invalid html document if the source contains
\AtBeginDocument directive. Minimal example comes here. The title is printed right at the top of the HTML code, i.e. even before the "<!DOCTYPE html" statement.

\documentclass[english]{minimal}
\usepackage[utf8]{inputenc}

\makeatletter
\AtBeginDocument{\@title}
\makeatother

\title{Minimal example}

\begin{document}
Test body.
\end{document}
