"must" has multiple meanings - it can indicate a requirement but it also

Though in general, I'm not a fan of writing in all caps, "MUST" removes the
ambiguity indicating that it is to be understood as defined, rather than
having its regular English meaning.

All caps for the words also helps the requirement statements stand out when
scanning through a document.

A few years ago I stayed in a B&B in England. The owner asked me: "Do 
you require toast in the morning?" This particular use of "require"
is not commonly used in the US (at least not on the West Coast) unless
toast is some kind of medical substance.

All of which goes to show that words have different meaning and also 
different USAGE, often location-based.
