The result of a call to Union is a permission that represents all the operations represented by both the current PnrpPermission and the specified permission. Any demand that passes either permission passes their union.

X.Union(X) returns an object that has the same value as X.
X.Union(Y) returns an object that has the same value as the object returned by Y.Union(X).
X.Union(a null reference (Nothing in Visual Basic)) returns an object that has the same value as X.
