VOID
expressions return no value but are used to
perform other work. The
VOID RENAME
expression changes the name of the specified
property for the current record.
The name of the property to change is given in an
OLD_NAME
expression node, and the new name is given in
a
NEW_NAME
expression node. Only the property name is
affected—the property values stay the same.
See the
EXPRESSION
element for DTD and attribute information.
