Item template description file

The template description file describes the template and the sequential actions to be executed in order to instantiate it.

There are three elements in the file:

• The item_template descriptor node. This describes the template and its characteristics.

• The instancing statements. The sequential steps needed to perform template instancing.

• The placeholder tags. Helper functional tags.
