Yes, if it's only ever called from the Saxon command line, then specifying
as="xs:string" achieves very little. It does however prevent someone
supplying, say, an integer using the command line syntax ?ICAO=42, or a date
using ?ICAO=current-date(). It also has documentary value, and it will come
into its own if someone in the fullness of time attempts to invoke the
stylesheet using a different processor or a different API.
