 == Limitations with the experimental version
 
 The {dpcpp} implementation of this extension currently has some important
-limitations.  The application must be compiled in ahead-of-time (AOT) mode
-using `-fsycl-targets=<special-target>` where `<special-target>` is one of the
+limitations with the `if_architecture_is` free function.  In order to use this
+feature, the application must be compiled in ahead-of-time (AOT) mode using
+`-fsycl-targets=<special-target>` where `<special-target>` is one of the
 "special target values" listed in the link:../../UsersManual.md[users manual]
 description of the `-fsycl-targets` option.  These are the target names of the
 form "intel_gpu_*", "nvidia_gpu_*", or "amd_gpu_*".
 
+The two APIs `device::ext_oneapi_architecture_is` and the
+`ext::oneapi::experimental::info::device::architecture` device descriptor are
+currently supported only for Intel devices (both GPU and CPU).  There is no
+support yet for Nvidia or AMD devices.
