marker.section.level integer
marker.section.level Control depth of sections shown in running headers or footers
2

## Description

The marker.section.level parameter controls the depth of section levels that may be displayed in running headers and footers. For example, if the value is 2 (the default), then titles from sect1 and sect2 or equivalent section elements are candidates for use in running headers and footers.

Each candidate title is marked in the FO output with a <fo:marker marker-class-name="section.head.marker"> element.

In order for such titles to appear in headers or footers, the `header.content` or `footer.content` template must be customized to retrieve the marker using an output element such as:

    <fo:retrieve-marker retrieve-class-name="section.head.marker"
                           retrieve-position="first-including-carryover"
                           retrieve-boundary="page-sequence"/>
