 ###### Encoding the `application/x-www-form-urlencoded` Media Type
 
 The role of `contentType` with `application/x-www-form-urlencoded` request bodies was not described in detail in version 3.0.3 and earlier of this specification.
-To match the intent of these fields and be compatible with version 3.1 of this specification, it is RECOMMENDED that whenever any of `style`, `explode`, or `allowReserved` are present with an explicit values, that the value of `contentType`, whether it is explicitly defined or has the default value, be ignored.
-Likewise, if all three of those fields are absent, it is RECOMMENDED that they be ignored, and that encoding be based on `contentType` alone.
+To match the intent of these fields and be compatible with version 3.1 of this specification, it is RECOMMENDED that whenever any of `style`, `explode`, or `allowReserved` are present with an explicit value:
+
+* The value of `contentType`, whether it is explicitly defined or has the default value, is to be ignored
+* If any of `style`, `explode`, or `allowReserved` are _not_ present with explicit values, then they are to be treated as if they were present with their default values
+
+However, if all three of `style`, `explode`, and `allowReserved` fields are absent, it is RECOMMENDED that:
+
+* All three keywords are to be entirely ignored, rather than treated as having their default values
+* Encoding is to be based on `contentType` alone, whether it is present with an explicit value or absent and treated as having its default value
 
 This makes the presence of at least one of `style`, `explode`, or `allowReserved` with an explicit value equivalent to using `schema` with `in: query` Parameter Objects, and their absence the equivalent of using `content`, but with the media type specified in `contentType` rather than through a Media Type Object.
