/**
 * This directive allows to dynamically enable and disable the validation with valdr.
 * All form elements in a child node of an element with the 'valdr-enabled' directive will be affected by this.
 *
 * Usage:
 *
 * <div valdr-enabled="isValidationEnabled()">
 *   <input type="text" name="name" ng-model="mymodel.field">
 * </div>
 *
 * If multiple valdr-enabled directives are nested, the one nearest to the validated form element
 * will take precedence.
