Composers
The Composer section of the Publishing Configuration document lists every composer configuration file (.ccf) defined on the Arbortext PE server. For each composer file, the document lists the absolute path to the .ccf file and every parameter defined for the composer. For each parameter, the document lists the parameter name, whether the parameter is required, the default value if one exists, the parameter type, and (for enumerated parameters only) legal parameter values.
