well, no - the message spec defines this object:
```
{
  "alias" : ["user@account.com", "someone@aerogear.org", ....],
  "category" : "someCategory",
  "deviceType" : ["iPad", "AndroidTablet"],
  "message": {
    "alert":"HELLO!",
    "sound":"default",
    "badge":7,
    "someKey":"some value",
    "anotherCustomKey":"some other value"
  },
  "simple-push": {
    "SomeCategory":"version=123",
    "anotherCategory":"version=456"
  }
}
```
