One option here would be to use the group prefix with a new DATE-RANGE 
property, so:

date1.ORG:...
date1.ADR:...
date1.EMAIL:...
date1.DATE-RANGE:20050101/20070601
date2.ORG:...
date2.ADR:...
date2.EMAIL:...
date2.DATE-RANGE:20070701/20100601

However, we do have to be careful with overloading the group prefix too 
much given that there is only one level of hierarchy in the prefix.

That said I have heard from some people that being able to maintain 
biographical information in a vCard would be very useful. Of course an 
alternative is to define a "BIO" property with a URL value pointing to 
where the bio information is stored. So the first question is does it need 
to be "by value" or "by reference"?
