Right now standard-annotations branch is an outdated fork of master branch with some stub annotations in it. Recently we've developed a way for merging in externally provided annotations into annotation manager by calling code similar to this:

\ns\of\package::register(Annotations::getManager());

To make this work we need to:

1. create separate repo (in the php-annotations organization)
2. move only annotations (not library code) to there
3. create composer package that would make them available for registration
4. describe somewhere how to use them

This way whoever wants to bring standard annotations up to date can do this in separate repo.
