/**
* @ngdoc directive
* @name patternfly.utils.directive:pfTransclude
* @restrict A
* @element ANY
* @param {string} pfTransclude specifies the type of transclusion to use.<br/>
* <strong>Values:</strong>
* <ul style='list-style-type: none'>
* <li> 'sibling' - The transcluded contents scope is a sibling one to the element where transclusion happens (default)
* <li> 'parent' - The transcluded contents scope is that of the element where transclusion happens.
* <li> 'child' - The transcluded contents scope is child scope to the scope of the element where transclusion happens.
* </ul>
*
* @description
* Directive for transcluding in directives and setting up scope of children of parent directives. This is a workaround
* for https://github.com/angular/angular.js/issues/5489
*
* @example
