/**
* Base class for String value format validators. Functionality covered in this base class:
*
* - accepts plain string and collections of strings as input
*
- each item is validated for collections of strings by {@link #doValidate(String, String, ValidationContext, ValidatorConfig)}
*
- null and empty values behavior should follow config, see {@link AbstractSimpleValidator} javadoc.
