There are no XML Schema types that represent bit sets (it would be a
somewhat unnatural type for text-based XML). The closest you can get
is by using base64Binary or hexBinary though for smaller bit sets it
would probably be more economical to use byte, short, int, or long.

Once you derive a type from base64Binary or hexBinary, you can use
type customization to completely override XML and/or binary
parsing and serialization code for this type which allows you to
choose pretty much any over-the-wire representation you like.
