You've covered the general concepts, but can you explain some of the details?
Such is a large, medium, small, x-small, x-large text field? What are the different sizes?
What happens if you only specify one of the two parts of a validation, i.e. minimum number of numbers and not the larger one? Vica versa?
There are so many things that can make a form properly finished here, but there is no documentation on how to use them. :)
