To make things simpler for users, we re-used the format of the update section
for anything map like in the modules, then you don't have to learn multiple
forms of attribute reference syntax.

Maybe we could rename it to 'map' to differentiate it, but you're the first 
person who's had trouble understanding the concept in the 8 months since
the release of v3.0.x (where this format is used in more modules) 
i'm inclined not to.

Alan is saying it uses the same format as an 'update' section in the policy,
language. Thought using the same section name might hint that... 

Is anyone else having trouble with understanding update blocks in rlm_cache,
rlm_ldap, rlm_couchbase? any suggestions to make them easier to use?

The cache module, you need to configure it to store the attributes you want
put back into the request when it's called again later.

I'm not sure how you think caching responses from the proxy server is going
to insert missing attributes into your SQL directory...

You'd need to use SQL xlat for that.
