non-normative sections using RTCSessionDescription

The specification defines the constructor of
RTCSessionDescription<http://www.w3.org/TR/webrtc/#rtcsessiondescription-class>as
taking a single RTCSessionDescriptionInit dictionary object as an
argument. The dictionary has the keys "type" and "sdp".

In two of the non-normative sections which create RTCSessionDescription
objects, a single "sdp" string is passed as an argument. Example 4 in section
13.1 <http://www.w3.org/TR/webrtc/#simple-peer-to-peer-example> does this.
Example 6 in section
13.3<http://www.w3.org/TR/webrtc/#peer-to-peer-data-example>does this.

It seems like these sections should be updated to reflect the changes to
RTCSessionDescription constructor specification.
