In addition to the Arbortext PE sub-process pool attributes, a pool may have parameters. Each pool parameter is defined by the Parameter element, which is a descendant of the SubprocessPoolContext element (which is a descendant of the SubprocessPool element) in e3config.xml.

When an Arbortext PE sub-process pool starts an Arbortext PE sub-process, it passes the Arbortext PE Request Manager global parameters and any Arbortext PE sub-process pool parameters and their values to the Arbortext PE sub-process, making them available to its Arbortext Publishing Engine applications.
