 ##### Fixed Fields
 Field Name | Type | Description
 ---|:---:|---
-<a name="encodingContentType"></a>contentType | `string` | The Content-Type to use for encoding a specific property. Default value depends on the property type: for `string` with `format` being `binary` - `application/octet-stream`; for other primitive types - `plain/text`; for `object` - `application/json`; for `array` - the default is defined based on the inner type.

 <a name="encodingHeaders"></a>Headers | `object` | A string map allowing additional information to be provided as headers, for example `Content-Disposition`.  Note `Content-Type` is described separately and will be ignored from this section.
 <a name="encodingStyle"></a>style | `string` | The Content-Type to use for encoding a specific property.  See (#parameterContent) for details on the [`style`](#parameterStyle) property. The behavior follows the same values allowed for `query` parameters, including default values.
 <a name="encodingExplode"></a>explode | `boolean` | When this is true, property values of type `array` or `object` generate separate parameters for each value of the array, or key-value-pair of the map.  For other types of properties this property has no effect. When [`style`](#encodingStyle) is `form`, the default value is `true`. For all other styles, the default value is `false`.
