Do any models support 3 types of token_type_ids?

On a page of the Transformers documentation here they mention that

Some models, like XLNetModel use an additional token represented by a 2 .

when referring to token_type_ids model input.

I looked on XLNetModel’s documentation and AFAIK it seems to only support 2 types.

Are there any models that support 2+ types of token?
