Summary
PHP 8.0's native attributes are not supporting nested attributes like doctrine annotations did. The only nested annotation in the ODM is an
@Index
which already could be used on a class-level, but wasn't advertised as such in the docs. The PR updates documentation and makes specifying@Index
annotations on class level a recommended way to go deprecating other ways of doing so.
