* "The XML-RPC API will be deprecated in the future. Use of this API is
not recommended, and existing consumers of the API should migrate to
the RSS and/or JSON APIs instead."
* "As a result, this API has a very restrictive rate limit and it may be
necessary to pause between successive requests." As such this also
gets around this issue for euscan.
