I am finding LOTS of namespaces in API documentation that are not fully-qualified (starting with \).
They need to be.
I don't even know where to start in fixing this but I'm filing this issue... It's a problem for the API module as well as IDEs if namespaces do not start with \ -- we discussed this a while back and although not everything with namespaces in documentation was agreed upon, this one point was agreed upon by everyone. Our standard is that they *must* start with \ and many of them in core don't.
