// class to encapsulate a qualifier list construct in the MOF grammer
// Since qualifier lists can appear before a lot of different metaelements,
// we have to collect them before we know where they go; then apply
// them to the metaelement one at a time.
// NOTE: KS. Sept 2003. Most of this could be replaced by CIMQualifierList.
// The one function that is unique is the applyQualifierList template.
