I'm talking about WebXR, which is for some reason the name of the standard developed by W3C.
"As such it may seem like WebXR and OpenXR have a relationship like WebGL and OpenGL, where the web API is a near 1:1 mapping of the native API. This is not the case with WebXR and OpenXR, as they are distinct APIs being developed by different standards bodies."
