Attribute groups are defined by specifying a unique identifier (id XML attribute) and a unique internal name (key XML attribute).
The optional specification of the internal name of the superordinate attribute type group (group XML attribute) allows attribute type groups to be arranged in a tree structure.
The internal name (key XML attribute) is stated in the subsequent name.
Use the AG_INVISIBLE attribute group pre-assigned by the system for attributes you do not want to be displayed in the PPM user interface in the Object attributes or Process attributes dialog box in the EPC view .
By default, this attribute group is not defined.
