The whereBlockedLocation is modified via its block(...) method to indicate where the expression blocked (for forward progress checking).

tells us if the property is non-empty. This is true if it is a constant non-empty expression (that is, is not ""), but it is also true if it is evaluated as a runtime expression that it is not allowed to return "".
Issue: are there properties which are string-valued, and where "" can in fact be returned at run time? Assumed no. This was clarified in an errata to the DFDL spec.

Note use of the stringOf(v) below. Turns out x.toString creates some crappy printed representations, particularly for Array[Byte]. It prints a useless thing like "[@0909280". Use of stringOf prints "Array(....)".
