Important gap: we don't specifically call out glTF under Inline node in Networking component.
Existing prose:
===============
9.4.2 Inline
[...]
The run-time system can support any number of 3D model resource types as long as those follow the abstract model definition (see 2.[RFC2077]), provide a registered content type (e.g. model/x3d-xml, model/gltf-bin, model/stl, etc.), and can be determined with some form of content negotiation (see 2.[RFC2616]). The run-time system must support at least one X3D type (e.g. model/x3d-xml) but can also support and negotiate any number of X3D encodings and (optionally) non-X3D representation formats.
===============
Recommended additions:
"Support for loading glTF assets also requires support for Shape component level 3."
Support levels:
4
Model support
Support for .gltf (model/gltf+json) and .bin (application/octet-stream)
