The language is simply meant to help illustrate how the framework might be 
used.   How do you think it will restrict usage?   How could it be improved?

In "section 3
 The token service is the assertion issuer; its
 role is to fulfill requests from clients, which present various
 credentials, and mint assertions as requested, fill them with
 appropriate information, and sign them."


As I understand, an assertion generated by a STS, is done flollowing thess 
steps:
1. Client presents credential and requests an assertion
2. STS generates assertion and sends to Client
Correct?

That may restrict the use cases that this assertion framework could support,
is it a must?
