afs:reply stores information about an elementary reply in a reply set. There is always exactly one afs:reply element per reply in a reply set page. Each afs:reply contains the following mandatory attributes:
- uri is the URI of the document, as provided to the PaF module while indexing.
- docId is the internal document identifier assigned to the document by the PaF module while indexing.
The uri attribute is generally used to build the target link enabling users to access the document represented by the reply. The docId attribute has no specific, public semantic other than being a unique key inside a given corpus.
