"

followed by an example in VRML encoding.

 

"standard node syntax" is only really applicable if the VRML encoding is used. The XML and JSON encoding use special ProtoInstance syntax instead and "standard syntax" becomes misleading.

 

A proposal would be 

 

"A prototyped node type is instantiated using keywords or standard node syntax. Adopting VRML encoding, the following ...

"

 

There may be a more concise way of clarifying as well.
