docutils.transforms.frontmatter.SectionSubTitle

This works like document subtitles, but for sections. For example,

<section>
    <title>
        Title
    <section>
        <title>
            Subtitle
        ...

is transformed into

<section>
    <title>
        Title
    <subtitle>
        Subtitle
    ...

For details refer to the docstring of DocTitle.
