In this paper we confront both the hadronic molecule and the hadro-charmonium interpretations of the \y with the experimental data currently available. We conclude that the data support the \y being dominantly a D1 D+c.c. hadronic molecule while they challenge the hadro-charmonium interpretation. However, additional data is necessary to allow for stronger conclusions.
