Detailed Description

Since ArithmeticExpression::flexiblyCalculate() creates Expression instances at runtime, we have the problem of having SourceLocationReflections for them in the case that we run into a runtime error, since the locations are always located at compile time.

This class simply delegates the reflection over to an existing expression.

I only managed to trigger this with "current() + 1", where current() evaluates to an invalid representation for xs:double.

Since: 4.5
