A GCV reference value.
The value of a GCV reference value is obtained from and stored to a GCV in an enclosing logical structure. It does not have a value of its own. It is not defined with a <definition> element. For example, a gcv-ref value in shim parameters refers to a GCV defined for the driver. The value referred to GCV is specified by the name attribute on the <gcv-ref> element.
Example 8-1 Example:
<gcv-ref name="placement-base"/>
