Clarify difference between network.local.*/network.peer.* and source.*/destination.* attributes

area:destination, area:network, area:source

Is your change request related to a problem? Please describe.

The docs for the network semantic conventions, source attributes, and destination attributes don't make it clear how network.local.*/network.peer.* and source.*/destination.* relate to each other.

The sense I get from the docs is that the network semconv attributes should be used in things like traces where a service is reporting on its own network communications, versus the source/destination attributes, which should be used by third-party services recording network transmissions between other applications.

Describe the solution you'd like

Clearly define the relationship between the two sets of attributes and advise in the docs when one or the other should be used.

Describe alternatives you've considered

No response

Additional context

I'm assisting the development of a Collector receiver that consumes NetFlow messages, and it isn't entirely clear to me how to translate the fields in NetFlow payloads to attributes in our semantic conventions given these two sets of attributes.
