Enhanced instance configuration
Detailed configuration of process instances can be carried out via the Instance Config reserved parameter.
This takes overrides of the INSTANCE_CONFIG parameter as possible values.
If an override of INSTANCE_CONFIG is saved for a process instance then, when it starts, the parameters in the override will be set to the configured values. This occurs before the template script is loaded, so the newly-defined parameters can be used by the template code.
Several different process instances can share an override of INSTANCE_CONFIG, or one per instance could be set up.
Currently the parameters that can be set via this enhanced process configuration are:
