These assets can be found on the X3D Specifications: XML Schema and DOCTYPE Validation page.
http://www.web3d.org/specifications
New assets: lists of all X3D elements and attributes, with default values, autogenerate from X3D XML Schema.
http://www.web3d.org/specifications/AllX3dElementsAttributes3.3.txt
http://www.web3d.org/specifications/AllX3dElementsAttributes3.3.xml
More new assets: X3D JSON Schema (manual) and X3D Object Model (autogenerated) by Roy Walmsley.
http://www.web3d.org/specifications/x3d-3.3-JSONSchema.json (experimental)
http://www.web3d.org/specifications/X3DObjectModel-3.3.xml (experimental)
Full documentation updates have been autogenerated for the XML Schema and DOCTYPE, available for X3D versions 3.0 through 3.3 plus experimental 4.0. Recommended version is 3.3.

Please note that X3D version 4.0 Schema and DTD are experimental and support specification development. All versions of these assets are maintained under open-source version control at
https://sourceforge.net/p/x3d/code/HEAD/tree/www.web3d.org/specifications
Changes are tested through validation regression testing of 3800+ open-source X3D scenes.
