A User System Defined Attributes (USDA) element must be created below a User Defined Attribute Group (UGROUP) element. To create a USDA element on the Home tab, in the Create group, select Create from the displayed drop-down list select USDA: User system defined attribute. A USDA element is created and is displayed in the Dictionary Explorer.

When a new element is created in the dictionary hierarchy using the Dictionary Explorer and if the Current Element Editor window is open, it automatically updates to display the default attributes for that element.
Note:
If the Current Element Editor window is not open, right-click in any Explorer window and select Current Element Editor.

After the creation of a new USDA element, use the Current Element Editor window to populate the attributes in the Current Element Editor.
