NOTAM experts out there?

I was wondering if anyone had a good reference that describes the NOTAM tracking system(s). The question I had came from a student, who asked:

"In the following NOTAM what does the M and L mean, and how about the numbers?

For example:

KCBM COLUMBUS AFBhttps://www.notams.jcs.mil/distribution/printQuery.html#top</U>

M0065/07 - CLASS C AIRSPACE ACTIVE. TRANSIENT AIRCRAFT OBSERVE PUBLISHED HOURS. 26 MAR 11:20 UNTIL 31 MAR 00:30 DAILY

L0004/07 - VOR DME OR TACAN RWY13L/31R UNUSEABLE. 09 MAR 15:42 UNTIL 07 JUN 23:59

KTUP TUPELO RGNL</U>
05/011 - RCAG 279.55 VICE 381.4 WIE UNTIL UFN

FDC 7/4456 - 7/4456 CANCELLED BY FDC 7/4472 ON 02/28/07 20:17 "

Now I was able to find what the M and the L mean (M means military safety notam, kind of the equivalent of a D series in civilian, and L means Local notam). FDC obviously is an FDC notam, but I was wondering if anyone was smart on how the numbering system works. For example, in the tupelo RCAG freq. change, what does 05/011 mean?

I have decoded these things, but they're in my prep material at home. The 07/4456 means 2007, notam 4456. There is a difference between the numbering systems per various types of notams, so the "05/011" may not be exactly the same. I'll have to check.

I think it has to do with continuity and cancellation of previous NOTAM
I'm not sure tho, I've wondered about these numbers before, I guess will find out today lol

05/011

Ok, the raw format for this is probably

!TUP 05/011

If so, the 05 is the 5th month, 11th notam in Tupelo's accountability location.
