The (only) relevant part of the „Classic VRML encoding“ spec is „Annex A: Grammar“:

https://www.web3d.org/documents/specifications/19776-2/V3.3/index.html

The grammar is written in Backus-Naur form. It is the „Scheme“ of classic encoding. Have a look at the rule „mfnodeValue“. You won’t find the symbol „routeStatement“ on the right hand side of that rule.

ROUTEs are only allowed:

1. At the top level of the scene
2. Inside the node body (between fields)

In my opinion it does not make much sense to forbid ROUTEs inside MFNode fields, and I am actually surprised that someone implemented it such strictly.

Bye,
