 ## Adding Gaussian Splats to Primitives
 
-As Gaussian splats are defined by a position color, rotation and scale, we both map to existing attributes and define new ones. These are attached to a primitive  by defining the `extensions.KHR_gaussian_splatting` property on that mesh.

 ### Splat Data Mapping
 
 To define a Gaussian splat, it must contain the following attributes:
 
-| Splat Data | glTF Attribute | Accessor Type | Component Type |
+| glTF Attribute | Accessor Type | Component Type | Description |
 | --- | --- | --- | --- |
-| Position | POSITION | VEC3 | float |
-| Color (Spherical Harmonic 0 (Diffuse) and opacity) | COLOR_0 | VEC4 | unsigned byte normalized |
-| Rotation | _ROTATION | VEC4 | float |
-| Scale | _SCALE | VEC3 | float |
+| POSITION | "VEC3" | 5126(FLOAT) | Gaussian Splat position |
+| COLOR_0 | "VEC4" | 5121(UNSIGNED BYTE) normalized | Color (Spherical Harmonic 0 (Diffuse) and opacity) |
+| _ROTATION | "VEC4" | 5126(FLOAT) | Gaussian Splat rotation |
+| _SCALE | "VEC3" | 5126(FLOAT) | Gaussian Splat scale |
 
 Standard PLY splat formats have opacity and color separate, however they are combined into the COLOR_0 attribute here.

 ### Transforming Gaussian Splat Data for glTF
 
+_This section is non-normative_
+
 The data output from the Gaussian splat training process that is stored in the typical PLY must be transformed before storing in glTF. These transformations make the data suitable for direct usage in glTF.
