review V51.3.3 and V51.3.4

[elarlang]

From the initial OAuth we have requirements:

#	Description	L1	L2	L3
51.3.3	[ADDED] Verify that Clients are utilizing the "scope" and "resource" parameters, respectively to determine the resource server they want to access.	✓	✓	✓
51.3.4	[ADDED] Verify that Clients are utilizing the "scope" and "authorization_details" parameters to determine the related resources and actions the access token are restricted to.	✓	✓	✓

Additionally to some formating improvements, we need to (re)validate the content, the need, the problem to solve and sections.

Verify that Clients are utilizing the "scope" and "resource" parameters, respectively to determine the resource server they want to access.

"Respectively" does not make sense here, does it?

Moreover, isn't the phrase backwards? I'm not sure I understand what it is we want to say here.
