title: Cloudant support of XML
body: <p>Have XML interfaces and data I need to support. Trying to decide if I could do that in Cloudant to take advantage of  DBaaS operational advantages. I could take in the XML, convert to JSON and store in Cloudant, then convert back to XML  to respond to a request. I've heard that the overhead of doing these sorts of conversions between XML and JSON are in the range of 20%. Is using Cloudant as a backend datastore for XML interfaces practical versus using native XML databases?</p>
