(Its really just pixeltexture in a separate file, with a few tricks). I use it for round-trip testing. But if you are desparate for web3d to own texture file formats it might be a good starting point.

we have ExternProtoDeclare node to define new nodes.

But you have brought up one of my bugbears with X3D, there is so much 
research build upon X3D/VRML97, but it seam like the source code get 
discarded once the paper is written.

some examples that should/could be added to X3D:
"Remote Rendering of Massively Textured 3D Scenes Through Progressive 
Texture Maps"
J-E. Marvie and K. Bouatouch
"A Vrml97-X3D Extension for Massive Scenery Management in Virtual 
Worlds" - Web3D 2004
  Jean-Eudes Marvie and Kadi Bouatouch
"Interactive Walkthrough of Large 3D Models of Buildings on Mobile Devices"
Alessandro Mulloni, Daniele Nadalutti and Luca Chittaro
"Streaming and Synchronization of Multi-User Worlds Through HTTP/1.1"
Jean-Eudes Marvie, Pascal Gautron, Pascal Lecocq, Olivier Mocquard and 
François Gérard

ps: I have contacted the authors
