Is the example not really in 4.1.3?

Yes, example 4.2 in section 4.1.3. An example for just displaying the validated value (i.e. without using the formatter) would be nice.

What do you mean w/ that?

It's meant to make clear that you can display only actual constraint attributes using the 1.0 parameter interpolation ({foo}) while everything else (validated value, any custom objects as possible since recently) must be displayed using an EL expression (${foo}).

There was a user who tried {validatedValue} without success .
