Hi Piotr, I have a small method DOM_validRef which basically uses this test:
if(Replace string($ref;"0";"")="") $valid:=false end if 64bit indeed uses 32 zero chars instad of 16, but this code handles both situations (and future ones, if we live long enough to make the transiton to 128bit systems...). My method also checks if all chars in the XML ref are valid hex chars (0-9 A-F), but that might be overkill.
