To access programmatically the value of a text-readable only system-defined attribute:
Attributes can also contain instances of user-defined classes of objects, or instances of variable and parameter classes. An object contained in an attribute of another object is called a subobject. For information on accessing the attributes of objects contained in an attribute, see Displaying the Subtable for an Attribute that Contains an Object.
Some attributes contain the text of a text-based item, such as a rule or procedure. These are called text attributes. You work with the text attribute of an item just as you would work with other named attributes.
Action attribute of an action button, the text attributes of rules and procedures, and the Item-configuration attribute of items. These are called compiled attributes. Items that have compiled attributes might have dependencies upon other items that affect their compilation status, as described in Using Compilation Configurations.
Distinguishing System- and User-Defined Attributes
An item's attributes are either system-defined or user-defined. The G2 system-defined classes define system-defined attributes for items. You cannot change the definitions of any system-defined attributes.
You can refer to most system-defined attributes of items. Some system-defined attributes, such as Notes, are text-readable only. You can refer to the text of such attributes, but not to their values directly. Accessing system-defined attributes is described in Chapter 12, Attribute Access Facility.
To access programmatically the value of a text-readable only system-defined attribute:
Form an expression that refers to the text of that attribute.
Notes attribute in a message that G2 posts to the Message Board workspace:

After you create a user-defined class with user-defined attributes, you can interactively edit any user-defined attribute in each instance of that class. Your KB can also conclude the value of any user-defined attribute.
To suppress interactive editing of editable attributes:
Define configurations that direct G2 not to display the edit choice on menus or to respond to mouse clicks that, by default, open the Text Editor.
