2. !begin/!end blocks for relations and hierarchies
You no longer need to use the "kformat" attribute to specify
relations and hierarchies. Just enclose them with !begin/!end.
For example:
!begin relation phonebook
916-555-1212; Mary
209-555-1212; John
!end relation phonebook
!begin hierarchy
person
/ John
/ Mary
/ Bill
!end hierarchy
