If the value of an argument is not a sequence, but a scalar, the scalar is treated as one-element sequence so it is added into the result. If the value of an argument is an empry sequence, the empty string is added into the result.
This function is not a part of XPATH 1.0 or XQUERY 1.0 libraries of standard functions.
