Description

If optional side regions on a page are established using parameters such as body.margin.inner, region.inner.extent, etc., then this parameter determines what happens at the corners where the side regions meet the header and footer regions.

If the value of this parameter is true, then the side regions have precedence and extend higher and lower, while the header and footer regions are narrower and fit inside the side regions.

If the value of this parameter is false (the default value), then the header and footer regions have precedence and extend over and below the side regions. Any value other than true or false is taken to be false.

If you need to set precedence separately for individual regions, then you can set two parameters that are normally internal to the stylesheet. These two parameters are normally set based on the value from side.region.precedence:

region.before.precedence
region.after.precedence
