valid decimal monetary value maybe overly restrictive

[marcoscaceres]

Following the robustness principle, if monetary values are strings, the algorithm for "valid decimal monetary value" should maybe trim.

Chrome throws, so probably should not trim.

Robustness principle is slowly falling out of favor because it encourages incompatible implementations. Strictly defining the boundaries of valid data is also useful in security sensitive contexts, such as payments.
