Code a GROUP definition statement to group cross-domain
resources. Each minor node in the group is defined with the values
specified on the operands on the GROUP definition statement unless
an operand is specified on the CDRSC definition statement.
Restrictions: - The LUALIAS operand is not supported on the GROUP definition statement
because an LUALIAS name must be unique to a CDRSC.
- The DELETE operand is not supported on the GROUP definition statement
because DELETE is valid only for model CDRSCs.
