...and a setting called "XSD" that's also ISO.

for now i'm backing away from the ECMA option - what i was thinking of  
would be exactly the same as "XSD" except rather than a timezone of  
'+00:00' it would be a 'Z'.  from some quick searching, it seems that  
XSD should be capable of understanding 'Z' rather than '+00:00' so if  
i was going to do anything i'd work towards making that change to 'XSD'.

however, as it turns out, the constraint i have that is requiring me  
to use 'Z' is not actually from ECMAScript 5 but from json-schema (http://tools.ietf.org/html/draft-zyp-json-schema-03#section-5.23 
).  XSD is fully compatible with ECMAScript 5 date time string format (http://es5.github.com/#x15.9.1.15 
)  so i'm going to sit on this again for a little while and think some  
more.  maybe try to convince json-schema to relax their definition of  
date-time format.

i'll be back when i have a clear picture of what i think makes the  
most sense.
