The Collection Specification Editor box is displayed if the current collection was not created using the RODM Collection Manager panels in NMC.
Caution: You can edit collections not created using the RODM Collection Manager panels in NMC, however, do not edit or re-send them if you are using regular expressions. Some characters in these expressions might be translated incorrectly (particularly tildes, carets and brackets). This problem becomes more acute with systems not running on code page 037.
