Why does a Qualifier match on a missing element? I have an Indentifier Instance configured as Identify By Qualifier. I get all the actual matches as well as anything where the element with the Qualifier defined is missing (minOccurs="0"). I've run several tests and I'm certain (enough) of the behavior. Someone must have experienced this before but I can't find prior art.
Further testing shows that the match of the missing element only happens when at there is at least one "actual" match in elsewhere in the document. Looking like a bug to me.
