xvalue symbols refer to two expressions: an lvalue and an rvalue. They are meant to be used with xvalue expressions. xvalue expressions are useful when a distinction must be made between the behavior of something (eg, a pascal function symbol) must change depending on whether it's an lvalue (assignment of the function's return value) or an rvalue (a call to the function, especially when the function takes no parameters).
