/** 
 * Use an Element (DOM) to store the information about a facet.
 * The intent of this facet type is to represent a facet
 * stored in an Collection attribute. Different facets can have different
 * attributes that we need to parse, but the only thing ManagedFacets need
 * to do, is to adjust the attributes "active" and "position". So, those
 * values are set directly on the Element, the other attributes aren't
 * touched.
