You could do this by defining a custom Finder that creates an instance of a
Resource of the appropriate subclass of Asset, assetType, given the request
URI /Asset/{assetType}/{id}.
But is it really necessary to have a resource type hierarchy that directly
mirrors your business domain? Why not just have an Asset field of
AssetResource that you initialize with AssetA, AssetB, or someone else's
subclass based on an {assetType} parameter?
