Detailed Description

Encapsulate a challenge to the validity of a label.

Since labels are valid at different servers at different times, it is not possible to know a priori whether a request with a specific label will be accepted by sufficient servers. This class encapsulates enough of a challenge to issue a new request when an old request is determined to be unable to complete.
