Subject: When enumerating entries, return the requests backend understands
X-Git-Url: http://git.cascardo.eti.br/?p=cascardo%2Fatompub.git;a=commitdiff_plain;h=0b5e74111b3dabb856855efc3f08318608d1b9bd

When enumerating entries, return the requests backend understands

To be able to map atom:IDs to backend requests, let the backend return
the mapping when enumerating the entries.
