The Document Properties Marker Macro contains a three columned table with the document properties. Authors will rarely add this macro to a page since this is the job of the template author.

Nevertheless the author used the macro, adds new properties to it or edits existing properties.

The three columns contain the name, the value, and controls of the property. Every property is on its own line.

The property control that is used the most is surely the hide control. It prevents the property from being rendered in the table. You may even opt to hide the whole table with the Hide parameter of the macro.
