The Comments node () contains developer comments about the implemented feature or other builder component. When added by default as a subnode to a node that you add in the Physics Builder, its called Developer Comments. These comments can include known capabilities and limitations, ideas for further development, and implementation detail that can be useful for maintaining and extending the functionality. You can add Comment nodes to other nodes in the Physics Builder tree when applicable. Right-click the node and choose Documentation > Comments. For nodes with comments (predefined Developer Comments and user-defined Comments), you can add additional Comments nodes as desired. For all Comments nodes with nonempty comments, the comments appear under Comments sections in the Settings window for the parent node, if you have selected the Display Comments in Settings checkbox under Comments in the Show More Options dialog.

In the Text section you add this information. You can use the character formatting tools above and below the text field to format parts of the text. The reference that is included by default, <ref entity="doc.entity">, is a general reference to the entity that the comment is about.
