It rather depends on what you want the output to be. There's no such thing
as a "binary string" recognized by the XDM type system. Perhaps you want a
string in which the one and zero bits are represented by Unicode characters
"0" and "1"? Or in which the octets are represented as a space-separated
sequence of decimal integers (0-255)?

Whatever the output you want, there isn't very much in the standard function
library to help you. Saxon has saxon:base64Binary-to-octets

http://www.saxonica.com/documentation/extensions/functions/base64binarytooct
ets.html

which may or may not help you.
