This is the basic API for creating data objects to be sent to other DataSource peers. Typically ds_init_data() will be used to create the object, then any number of the add functions used to add field, value pairs to the object. There are various functions allowing different data types to be added.
#define DS_FIELDS_SEPARATOR |
Defines the separator between multiple type 2/type 3 or permission row updates within a single packet.

This function should be used instead of setting _ds_data::subject directly since this function respects any patterns defined using the add-pattern
configuration option.
