This is a Librarian design that matches the specifications of the PO file.
Member name of PO file cannot start with a number.
AllFusion CA-Librarian uses the module name as the member name, unless the module name begins with a numeric character, in which case AllFusion CA-Librarian prefixes the letter Z to the first seven characters of the module name to create the member name (Zxxxxxxx).
