Generic Processing Instructions
When Arbortext Editor reads a processing instruction (PI) that it does not recognize, it writes the PI exactly as it was read using the _pi tag.
This is primarily for preserving PIs from other systems. If tag display is set to full, these PIs display in the Arbortext Editor window (unless an application has used the tag display command to suppress their display).
You can modify the PI through the Arbortext Editor interface or using ACL commands for modifying attributes, and modifying the Text attribute.
For example, you could create the <?My own PI.> PI by doing the following:
it _pi
mt Text="My own PI."
The write-nopi command will not delete generic PIs.
