+== Extension to `enum class aspect`
+
+[source]
+----
+namespace sycl {
+enum class aspect {
+  ext_oneapi_native_assert
+}
+}

+If device has the `ext_oneapi_native_assert` aspect, then its Device-Side
+Runtime is capable of native support of `assert`. That is, safe implementation
+is used. If device doesn't have the aspect, then fallback implementation is
+used.
