Undefined name: "enum"

[Tim Robertson]

Hi all,

I am new to avro, and using it to implement an http RPC transport
layer to allow distributed components to push to a centralised event
log.

I have the following types in my .avpr:

 "types": [
     {"name": "Event", "type": "record",
      "fields": [
          {"name": "message", "type": "string"},
          {
                "type": "enum",
                "name": "sourceComponentType",
                "symbols" : ["OCCURRENCE_HARVESTER", "CHECKLIST_HARVESTER", 
"USER"]
          },
          {"name": "instanceId", "type": "string"},
          {"name": "sessionId", "type": "string", "default": null},
          {"name": "count", "type": "int", "default": 0},
          {"name": "sourceId", "type": "string"},
          {"name": "userId", "type": "string"},
          {
                "type": "enum",
                "name": "level",
                "symbols" : ["DEBUG", "INFO", "WARN", "ERROR"]
          },
          {"name": "agentId", "type": "string"},
          {
                "type": "enum",
                "name": "objectType",
                "symbols" : ["OCCURRENCE", "NAME_USAGE"]
          },
          {"name": "objectId", "type": "string"},
          {"name": "message", "type": "string"},
          {"name": "sensitive", "type": "boolean", "default": "false"}
      ]
     }

but on protocol compilation get:

Can someone spot an error please?  I'm on 1.3.3 and just copied the
example in the docs on
http://avro.apache.org/docs/1.3.3/spec.html#Enums

Thanks,
