Syntax
  repeat over data-attribute attribute-name of (attribute-reference)
     local-declaration*
     action*
  again
The repeat-over action can be applied to data-attribute references in the same way as attribute references. 
Inside repeat over, the data attribute being iterated over can be referred to using either the data-attribute herald or the attribute herald. 
The "z" format modifier is used to turn off translate rules in order to make the "%v" format item behave exactly like the attribute reference.
