How to make compound keys with mapper?

[GA-4]

Hello guys,

could you please send me a quick example of a mapper with two fields  
as primary key? for instance a primary key including both a Long field  
and a DateTime field.

Thanks in advance,

GA

Sorry, Mapper does not support compound primary keys. :-(

What would it take to add support?

At the very least changes to Schemifier.  It would also entail more support and testing for compound fields (MappedPassword being the only example and I consider it a mistake.)

All in all, it'd be > 1 man-week for me and probably close to 1 man-month for someone less familiar with the ugly underbelly (whoops did I say that) of Mapper.
