/**
 * Part of project jwht-htmltopojo
 *
 * Example implementation of an  {@link AcceptIfResolver}.
 *
 * 
 *     This one will extract one attribute of the given HTML Element
 *     {@code {@link Element}} and check if it matches with the
 *     submitted regex.
 * 
 *
 * 
 *     You have to provide an {@link AttrRegexCheck} annotation on top of
 *     the corresponding field in order for this deserializer to work properly.
