Parser fails on TSQL "NEXT VALUE FOR"?

[manticore-projects]

Parser 4.1 can't parse:

-- SELECT
select /*+PARALLEL*/
	a.id_fee_type
	, concat('New fee ' , a.id_fee_type)
    , NEXT VALUE FOR cfe.id_fee_type_ref
	from (
	select distinct
		id_fee_type
	from
		cfe.SCHEDULE
	union select
		id_fee_type
	from
		cfe.ONE_TIME_PAYMENT
	) a left join cfe.FEE_TYPE b on a.id_fee_type=b.id_fee_type
where
	b.id_fee_type is null
	and not a.id_fee_type is null
;

I dug into the code and found that NextValExpression deparses into NEXTVAL FOR (and the query gets parsed with NEXTVAL FOR).
However, this does not seem to be valid TSQL according to https://docs.microsoft.com/en-us/sql/t-sql/functions/next-value-for-transact-sql?view=sql-server-ver15. Is this a bug or a feature? (I am not MS SQL Server guy).
