How does one create a schema for an array of records?

For example, I have a record schema for a user (name and id; see
below).  I would like to serialize an array of users.  I've tried
various combinations of things, and I'm not getting it to work.

Thanks,
Curtis


  [
  {
  "name": "User",
  "type": "record",
  "fields": [
    {"name": "name", "type": "string"},
    {"name": "id", "type": "int"}]
  },
  {
  "type": "array", "items": "User"
  }
  ]}

We do it like so:

"name": "AttributeMappings",
"type": {
        "type": "array",
        "items": {
                "name": "AttributeMapping",
                "type": "record",
                "fields" : [
                        {"name": "Key", "type": "long"},
                        {"name": "Value", "type": "long"}
                ]
        }
}
