Functions missing from metadata document?

[thomasmatecki]

Within the example, we have two classes registered in the data model(EntityServiceRegistar;49): oDataEdmRegistry.registerClasses(Lists.newArrayList( Person.class, GetAverageAge.class ));

I expect a function to be present within the metadata document( in Schema SDL.OData.Example) like this: <Function Name="GetAverageAge"> <ReturnType Type="Edm.Double"/> </Function>

Here is what I see: metadata.txt
