Its much easier in json, as documents are embeddable, without so much 
syntactic noise.

 From our tiburon product, boot.json file:

{
    "servers" : {
       "default" : "192.168.108.250"
    },
    "boot" : {
       "default" : {
          "address" : "servers.default",
          "port"    : "3000"
       }
    },
    "nfs" : {
       "default" : {
          "address" : "servers.default",
          "mountpoint" : "/data/nfs"
       }
    },

    "targets" : {
      "nfs" : {
        "CentOS6.3_x64" : {

	//
	}
        }
       }
}

Very easy to parse with existing libraries, and mere mortals (and text 
editors) have a fighting chance at working with this.

As someone who worked with XML for more than a decade, and JSON for a 
few years, none of our projects are ever going to use XML again if we 
can avoid it.  Since all of these json documents map nicely into various 
noSQL dbs (MongoDB, rethinkDB, etc.), its fairly trivial to go from 
config file to replicated data store.  Which, I believe, solves another 
long standing problem.
