+Issues
+
+  1) Should TEXTURE_MAX_ANISOTROPY_EXT be accepted by SamplerParameter*?
+
+  Yes, for implementations supporting sampler objects. The per-texture sampling
+  state is overridden by the sampler object state, if present. The anisotropy
+  parameter should not be an exception, as this would reduce the usefulness of
+  sampler objects when anisotropic filtering is supported. This also matches
+  the interaction described in ARB_sampler_objects, and the same behavior is
+  still expected for API versions with core support for sampler objects.
+
 Revision History
 
+  2018-05-23 (Nicolas Capens) - clarify interaction with sampler objects.
+
   11/12/14 (Jon Leech) - Fix spelling of TEXTURE_MAX_ANISOTROPY 
   (public Bug 1263).
