<br>
While .gltf is also valid JSON, using a generic .json extension for<br>
them feels "unnecessarily generic". It would be like using .xml<br>
instead of .x3d for models in X3D XML encoding.<br>
<br>
That being said, why do you validate with X3D JSON schema all *.json?<br>
Shouldn't X3D JSON also have a specific extension, not use generic<br>
.json?<br>
