The problem with the previous type attribute values inclusive, bulk and 
single was that this really combined two different lists, resulting in 
ambiguity. In particular, a "single" date can be either inclusive or bulk:
1920-1945, bulk 1940
1940
2 January 1940

I'm surprised that "single" was mapped to datechar since this doesn't 
seem like an appropriate use of datechar. Is it necessary to encode the 
fact that a date is a single date? If you are implementing date 
searching, I suspect the use of the NORMAL attribute would be more 
effective.
