When you have created a data template for Message data (see Creating data templates for Message data), data template nodes may be empty (no values defined) or contain static values. Nodes replicated from the Message data contain the static sample data defined in the Event, and nodes created in the Data template panel may contain static values or be empty.
For example, you can use recurse on the message node to automatically generate the rules for the entire message sub tree (see
Transformation for Message data using meta rule).
