Returns true if the first argument is less than the second.
xs:hexBinary values. Also used in the
definition of the "ge" operator.op:hexBinary-less-than( $arg1 as xs:hexBinary,$arg2 as xs:hexBinaryxs:booleanThe function returns true if any of the following conditions is true:
$arg1 is zero-length (contains no octets) and $arg2 is
not zero-length.
Neither argument is zero-length, and the first octet of $arg1 is less
than the first octet of $arg2, treating the value of the octet as an
unsigned integer in the range 0 to 255.
Neither argument is zero-length, the first octet of $arg1 is equal to
the first octet of $arg2, and the xs:hexBinary value
formed by taking all octets of arg1 after the first is less than the
xs:hexBinary value formed by taking all octets of
arg2 after the first.
Otherwise, the function returns false.
