+The ``sycl_kernel_entry_point`` attribute facilitates the generation of an
+offload kernel entry point, sometimes called a SYCL kernel caller function,
+suitable for invoking a SYCL kernel on an offload device. The attribute is
+intended for use in the implementation of SYCL kernel invocation functions
+like the ``single_task`` and ``parallel_for`` member functions of the
+``sycl::handler`` class specified in section 4.9.4, "Command group ``handler``
+class", of the SYCL 2020 specification.
+
+The attribute requires a single type argument that specifies a class type that
+meets the requirements for a SYCL kernel name as described in section 5.2,
+"Naming of kernels", of the SYCL 2020 specification. A unique kernel name type
+is required for each function declared with the attribute. The attribute may
+not first appear on a declaration that follows a definition of the function.
+
+The attribute only appertains to functions and only those that meet the
+following requirements.
+
+* Has a ``void`` return type.
+* Is not a non-static member function, constructor, or destructor.
+* Is not a C variadic function.
+* Is not a coroutine.
+* Is not defined as deleted or as defaulted.
+* Is not declared with the ``constexpr`` or ``consteval`` specifiers.
+* Is not declared with the ``[[noreturn]]`` attribute.

No, we dropped the function template requirement as being unnecessary. This
permits an implementation to declare single purpose kernels if desired.
