Issue 130: Section 9.4: maxTemporalLayers and maxSpatialLayers from Bernard Aboba on 2014-07-14 (public-ortc@w3.org from July 2014)

Currently, we have:

unsigned short            maxTemporalLayers = 0;
unsigned short            maxSpatialLayers = 0;

Some questions:

a. Assuming these attributes are only for SVC, how are the maximum number of simulcast layers indicated? ]
b. What happens if a developer tries to exceed the maximum number of simulcast layers (e.g. by doing "poor person's simulcast", creating multiple RTCRtpSender objects)?
c. If maxTemporalLayers = 1 or maxSpatialLayers = 1, isn't this the same as saying that temporal scalability (or spatial scalability) isn't supported?
