Returns true if the first argument is less than the second.
xs:hexBinaryvalues. Also used in the definition of the "ge" operator.
The function returns
true if any of the following conditions is true:
$arg1 is zero-length (contains no octets) and
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
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
