The SchemaProperty Object allows the definition of input and output data types nested within the properties attribute of a Schema annotation. These types can be objects, but also primitives and arrays. This object is an extended subset of the JSON Schema Specification Wright Draft 00.

    whether or not this schema is read only
    
    Default:
    
    false
- - writeOnly
```
public abstract boolean writeOnly
```
    Relevant only for Schema "properties" definitions. Declares the property as "write only". Therefore, it MAY be sent as part of a request but SHOULD NOT be sent as part of the response.
    If the property is marked as writeOnly being true and is in the required list, the required will take effect on the request only. A property MUST NOT be marked as both readOnly and writeOnly being true.

    Default:
    
    {}
- - defaultValue
```
public abstract java.lang.String defaultValue
```
    Provides a default value. The default value represents what would be assumed by the consumer of the input as the value of the schema if one is not provided.
    Unlike JSON Schema, the value MUST conform to the defined type for the Schema Object defined at the same level.
    For example, if type is string, then default can be "foo" but cannot be 1.
    
    Returns:
    
    the default value of this schema
    
    Default:
    
    ""

    Returns:
    
    the maximum number of items in this array
    
    Default:
