Validation Support

[Michael Strauß]

I would not be in favor of adding any particular data validation
framework to JavaFX. Data validation comes in all kinds of different
shapes and sizes, which makes it a good fit for (opinionated)
third-party libraries. However, I fully agree with John that JavaFX
should provide more APIs that can only realistically be implemented in
FX. I've proposed a "significant interaction" API, which is crucial
for many data validation scenarios:
