Cannot locate find function called in a procedure

I am quite new to SQL Server. I have an issue where we have a stored procedure called sys.sp_MSallocate_new_identity_range (see part of logic below). It makes reference to two functions neither of which I can locate. 

if (**sys.fn_MSmerge_isrepublisher**(@artid)=0)
    begin
        declare @publisher_max_used numeric(38,0)
        declare @pubid uniqueidentifier
        declare @pub_ranges_needed tinyint
        declare @pub_refresh_constraint bit

        select @pubid = subid, @publisher_max_used = max_used from dbo.MSmerge_identity_range 
            where artid = @artid and is_pub_range = 1 and (**sys.fn_MSmerge_islocalpubid**(subid)=1)
        if @pubid is NULL
        begin
            raiserror(20663, 16, -1)
            return 1
        end

Running the stored prcoedure with appropriate parameters - returns a result :

declare @p4 smallint
set @p4=2
declare @p5 numeric(38,0)
set @p5=31001
declare @p6 numeric(38,0)
set @p6=32001
declare @p7 numeric(38,0)
set @p7=32001
declare @p8 numeric(38,0)
set @p8=33001
exec sys.sp_MSallocate_new_identity_range 'B551D87F-5457-2102-9E6A-DD4EB44B1DD1','4EB5E2D0-3FC1-4D77-B894-5D57C433D0B2',2,@p4 output,@p5 output,@p6 output,@p7 output,@p8 output,N'dev_02',N'PPC04 - 21a535007fd8',N'My Documents\Assets\assets.sdf'
select @p4, @p5, @p6, @p7, @p8

i.e This works and returns a result. All Good - but I cannot locate the functions embedded within the stored procedure i.e. sys.fn_MSmerge_isrepublisher or sys.fn_MSmerge_islocalpubid.

I have looked in sys.objects and sys.all_objects where name like '%fn_MSmerge%'.

I have managed to trace the SQL and the trace gives an ObjectID and I can see the statement executing. The trace tells me it is a function - 20038 - FN - and gives me an objectid of 563464549 - but cannot find by looking in sys.objects for the database

Any help/advice gladly accepted.

These object definitions do seem to be hidden. If you connect via the DAC and run

SELECT OBJECT_DEFINITION(OBJECT_ID('sys.fn_MSmerge_islocalpubid'))  AS
       [processing-instruction(x)],
       OBJECT_DEFINITION(OBJECT_ID('sys.fn_MSmerge_isrepublisher')) AS
       [processing-instruction(y)]
FOR XML PATH('')

you can see them though. The definitions for my version of SQL Server are as below

create function sys.fn_MSmerge_islocalpubid (@pubid uniqueidentifier)
returns bit
as
begin
    declare @publisher_db sysname
    declare @publisher sysname

    select @publisher_db = publisher_db, @publisher = publisher 
    from dbo.sysmergepublications 
    where pubid = @pubid
    if @publisher_db is NULL or @publisher is NULL
        return 0

    if @publisher_db = db_name() and UPPER(@publisher) = UPPER(publishingservername())
        return 1

    return 0
end


create function sys.fn_MSmerge_isrepublisher (@artid uniqueidentifier)
returns bit
as
begin
    if exists (select pubid from dbo.sysmergearticles where artid = @artid and (sys.fn_MSmerge_islocalpubid(pubid) = 0))
        return 1

    return 0
end
