Minor Description
Add to https://docs.couchbase.com/server/current/n1ql/n1ql-language-reference/metafun.html#meta a NOTE or example showing how to retrieve document virtual XATTRs, likely with a cross-link to https://docs.couchbase.com/server/current/learn/data/extended-attributes-fundamentals.html#virtual-extended-attributes.
It should note clearly that access to virtual xattrs is an expensive operation that will impact query latency.
e.g.
select meta().xattrs.`$document` from default use keys["key1"] |
