Base64 output is not stable

[Paolo F Cantoni]

EA uses Base64 encoding in the XMI for (amongst other things) Model Documents. (dt:dt="bin.base64" - in the XML entry).

However, each time you do an export, even if there has been NO change to the entire repository, the encoding changes.

This makes it difficult to use file comparison products to ensure the consistency of output.

I see no reason (not being a Base64 expert) why they should be different.

Steps:
Export a package containing Model Documents.

Save export.

Reexport - changing nothing.

Compare the two outputs - the Base64 encoded data is different.
Can any Base64 experts explain if this phenomenon is inherent in Base64?
