[Heb-NACO] $2 edtf in 374

[Robert Talbott]

Folks:

Q:

How are we handling Hebrew year dates converted to Gregorian "or" year 
dates in fields other than the 046?  Specifically, I'm creating a record 
for someone who was the "President du Tribunal Rabinique, 5700-5710."  
Unfortunately, the specific side of the Gregorian divide is not given 
for either of these years, thus 5700-5710 recombobulates to 1939 or 
1940-1949 or 1950.  Per the DCMZ for 046 (which theoretically should be 
applicable for other non-046 fields), dates like this should follow edtf 
formatting instead of  ISO 8601.

374  President du Tribunal Rabinique $s [1939,1940] $t [1949,1950] $2 edtf

Sadly, the $2 is recognized in the 374 as only applying to the $a 
portion of the field.

My questions:

1) Since I cannot include $2 edtf, are edtf-style dates forbidden?

2) If "Yes"  is the response to #1, then how should the 1939 or 
1940-1949-1950 fiasco be expressed?

Thanks in advance,
