classify this reaction?

2HCl(aq) + CaCO3(s) CaCl2(aq) + CO2(g) + H2O(l) i would have thought that this was a double displacement reaction but there are three products; so what type of reaction is this?
Well, here's my reaction:

Looks like a neutralisation to me. HCL is acidic and CaCO3 is a base and they react to form a salt and water (as well as the carbon dioxide, it seems)
