KeyRef check

During a keyRef check, the following object controls are made.

KeyRef name and code uniqueness

An element cannot contain two keyRefs with identical names and/or codes.

Manual correction	Automatic correction
Rename one of the keyRefs	Renames the keyRef by appending a
	number to its name or code

Undefined reference

A keyRef must contain a reference to a key or a unique constraint.

Manual correction	Automatic correction
In the keyRef property sheet, define a	—
reference to a key or a unique constraint
with the Reference dropdown listbox

Existence of fields

A keyRef must contain at least one field.

Manual correction	Automatic correction
Add at least one field to the keyRef or	Deletes unassigned keyRef
delete the keyRef. For example:
@numEmployee

For more information on fields, see section Defining an identity constraint field in chapter Building an XML model.
