For testing a base64Binary XML type at one of my projects I needed an example of a base64 encoded file content. There is a simple command for that (at least when you are working on a Mac). For a file called ‘abc.pdf’ the command is:
openssl base64 -in abc.pdf -out encoded.txt
The result is a file ‘encoded.txt’ with a base64 decoded string:

As you can see I make use of the openssl library that comes with Mac OS X Maverick. You can use this content in your (XML) messages as a Base64 string for testing purposes.
