-In this example, the contents in the `requestBody` MUST be stringified per [RFC1866](https://tools.ietf.org/html/rfc1866) when passed to the server.  In addition, the `address` field complex object will be stringified.
+In this example, the contents in the `requestBody` MUST be encoded per [RFC1866](https://tools.ietf.org/html/rfc1866) when passed to the server.  In addition, the `address` field complex object will be serialized to a string representation prior to encoding.
+
+When passing complex objects in the `application/x-www-form-urlencoded` content type, the default serialization strategy of such properties is described in the [Encoding Object](#encodingObject)'s [`style`](#encodingStyle) property as `form`.
+
+With this example, given an `id` of `f81d4fae-7dec-11d0-a765-00a0c91e6bf6` and a US-style address (with ZIP+4) as follows:
+
+```json
+{
+  "streetAddress": "123 Example Dr.",
+  "city": "Somewhere",
+  "state": "CA",
+  "zip": "99999+1234"
+}
+```
+
+Assuming the most compact representation of the JSON value (with unnecessary whitespace removed), we would expect to see the following request body, where space characters have been replaced with `+` and `+`, `"`, `{`, and `}` have been percent-encoded to `%2B`, `%22`, `%7B`, and `%7D`, respectively:

+```
+
+Note that the `id` keyword is treated as `text/plain` per the [Encoding Object](#encodingObject)'s default behavior, and is serialized as-is.
+If it were treated as `application/json`, then the serialized value would be a JSON string including quotation marks, which would be percent-encoded as `%22`.
+
+Here is the `id` parameter (without `address`) serialized as `application/json` instead of `text/plain`, and then encoded per RFC1866:
