Thanks for replying to this, Darin, and your reply is correct. There's a 
way around this issue of needing a separate element name wrapping a 
collection, though, if you're only doing input.

Instead of defining the repeated elements as a collection, just define 
them as simple values with set-methods. Then with allow-repeats="true" 
on the containing <structure> the set-method will be called repeatedly 
for each time the element is seen.

That only works for unmarshalling, though. If you need to be able to 
marshal out documents as well you'd need to define a separate binding 
(with a <collection>, and without the flexible="true") for that side of 
things.
