MEMBERCNAME supports multiselect. That is, you can use it to return the captions of multiple elements that are stored in MLS-XML.
For example, a report variable called rv_multi contains this MLS-XML: 
                           		
                           
                        		
                        <?xml version="1.0" encoding="utf-16"?>
