[presentation-api] conflict description for uniquely identifying a presentation session

schien has just created a new issue for 
https://github.com/w3c/presentation-api:

== conflict description for uniquely identifying a presentation 
session ==
In common idioms section, we have two different description for the 
unique identifier of a presentation session: 
```
A valid presentation session identifier consists of alphanumeric ASCII
 characters only, is at least 16 characters long, and is unique within
 the set of presentations.
```
and
```
The presentation session URL and presentation session identifier 
uniquely identify the presentation session.
```
I think we should follow the second description. However this brings 
up another issue on presenting side for many-to-one join session: how 
can a presenting page accept a incoming join request (which specify an
 URL and an session id) and still maintain the unique identifier 
within the set of presentation session.
