HA 02405.003 Numbering of the Preambles
Renumbered from HALLEX section II-4-0-3
The preambles follow a 4-digit numbering system similar to that used in 
other HALLEX Volume II issuances. 
The Roman numeral identifies the HALLEX 
Volume, i.e., the Roman numeral for each preamble is "II." 
The first digit identifies the HALLEX 
Part, i.e., "4." 
The numerical order in which the preambles are published determines the 
last three digits, e.g., the first preamble published is 
HA 02405.001.
