3.2.b Locators in attributes or elements?



 3.2.b Should the locators of a general link be packaged in attributes
 as in HyTime, or as child elements as in the initial draft? 

Consensus of the ERB is to use subelements to package up locators in
extended links.  The simplicity of doing it all with attributes was
appealing, but there are two big problems:

 - it becomes awkward to associate locators with individual metadata
 - it becomes necessary to overload attribute values with space-separated
   tokens or some such that are used to help interpret the rest of
   the attribute values.

Eliot assures us that this is legal HyTime, given the right grove plan.
