WRT Malpensa - I don't know the place but the ICAO Standard signage for a runway holding position leading onto a precision instrument runway where there is only one holding position (which seems to be what you describe) does not include 'CAT II/III' but looks like the sign used for a visual or non-precision runway and just says 'A 27' or whatever. See ICAO Annex 14 - Figure 5-25 on page 92 illustrates it nicely.
