Please define rpc.xml
I see RSS feeds described more than one way.
I see a xml file (perhaps that pertains ONLY to a sitemap?)
and I see url syntax to the effect of:
/feed
/rss
/rss=2
and then there are the rcp.xml
what is that?
for example the feed from a flickr RSS url is somehow different than a standard blog. The flickr one starts with rpc
what does rpc denote?
thanks
