Attribute type

I just went ahead and implemented RESP3 for the Node.js redis parser and I struggle to see the how this can be delivered to the user in a useful way.

It is not clear if the attribute alone should be delivered to the user or if it should be delivered in combination with the actual corresponding data (which IMHO would make sense). The latter however requires the parsing logic to become more complex in cases for aggregated data types such as arrays, maps and sets.

It is also not clear when exactly the data should be delivered as in: immediately after the attribute is parsed or after the top level is done parsing? (This is again about aggregated data types)

Would it not be better to just provide the very same information as push information that just contains the actual data on top of the attribute? It's of course extra data to parse but it would simplify the parser logic. Right now the attributes somewhat seem out of line for me compared to the rest of the spec.
