/**
 * This exception is thrown if the matching between the linkage of a
 * declared variable and the combined linkage of a used variable in a
 * transformation have incompatible values. An example for such an
 * incompatability is having declared a variable of type input, but
 * using it as ouput. The exception will also be thrown, if multiple
 * usages of a bound variable use incompatible linkages, e.g. the same
 * variable is used with linkage NONE in one instance, and with any other
 * linkage in the same transformation at another place.<p>
 *
 * A method is not required to declare in its throws clause any
 * subclasses of RuntimeException that might be thrown during the
 * execution of the method but not caught.
