<cloud> sub-element of <channel>
<cloud> is an optional sub-element of <channel>.
It specifies a web service that supports the rssCloud interface which can be implemented in HTTP-POST, XML-RPC or SOAP 1.1.
Its purpose is to allow processes to register with a cloud to be notified of updates to the channel, implementing a lightweight publish-subscribe protocol for RSS feeds.
<cloud domain="rpc.sys.com" port="80" path="/RPC2" registerProcedure="myCloud.rssPleaseNotify" protocol="xml-rpc" />
In this example, to request notification on the channel it appears in, you would send an XML-RPC message to rpc.sys.com on port 80, with a path of /RPC2. The procedure to call is myCloud.rssPleaseNotify.
