## Remarks

The D3D\_NAME values identify shader parameters that have [predefined system-value](https://learn.microsoft.com/en-us/windows/win32/api/d3d11shader/ns-d3d11shader-d3d11_signature_parameter_desc) semantics. These values are used in a shader-signature description. For more information about shader-signature description, see [D3D11\_SIGNATURE\_PARAMETER\_DESC](https://learn.microsoft.com/en-us/windows/win32/api/d3d11shader/ns-d3d11shader-d3d11_signature_parameter_desc).
