DirectX Anisotropic Filtering Option Levels and Future Proofing It

Ok so i have a configuration program for a 3d directx application. When querying the AF level i get a 16. If 16 is available will 8, 4 and 2 always be available? and when / if in the future levels go up to 32 / 64, will these lower values be available too?

will this always be the case? can i always divide the max af level by two until i arrive at 2 to obtain all the possible af levels? Lastly if that is not the case is there a way to query directx much in the same way you can check if the hardware supports a multi-sample level to see if it supports the select anisotropic filtering level?

Yes, the query is for the maximum anisotropy, not the one value you can set it to. Also, there's nothing I can find in the docs that says that the anisotropy you set must be a power of two (though admittedly, I only did a quick search).
