Multiple properties of the same type with default value

Hello,
your example does not work if you have multiple properties of the same type with default value.
For example, I've added a property of type string and I want to set a default value.
```typescript
"properties": {
"name": { "type": "string", "default": "Emmerich" },
"test": { "type": "string", "default": "myTest" },
"position": { "$ref": "#/definitions/Coordinates" },
"hitPoints": { "type": "integer", "default": 100 }
},
```
The result is an exception
```
Error: Inconsistent default values

Can you give us the right way to do that ?

thank you
