The <?blockindentstart> and <?blockindentend> commands set the distance at which text should be indented from the edges of the block content area. Their expected use is to indent all lines in a block by the same amount, with any <?blockindent> command present adding an additional indent to the first line. They behave in the same way as <?blockcellpadl> and <?blockcellpadr>, respectively, with the exception that these indents are sensitive to the <?blockprogression> instruction and will flip when flowing from right to left.

Give the commands a negative value to achieve an outdent effect.

The example below sets up a simple list block structure where the text will be indented at 20mm from the edges of the block. The list item label will be outdented at 18mm, and the label content will appear right aligned at 10mm.
