The top-level afs:replies element has two child elements:
- The optional afs:header element describes the context of the query. This header can include error messages when a problem has occurred while replying.
- The list of afs:replySet elements (one per reply set) is made of one element per agent reply set, for example, one for the SpellChecker and one for the full-text search. The list can be empty, in which case the query has not produced any result.
