Hi Mark,
That's right.
But checking if each char i of the string is in "abcdefghijklmnopqrstuvwxyz1234567890+/=" will take care of spaces.
I hope or am I wrong?

I use base64 for making text and binary data websafe. Knowing what my file format is makes it easy by file types and file extensions. This is fine for my needs but lousy for generic or unknown files. I was using numbers and spaces to get around the 32 kbt per line problem in fields. I now see that the spaces are not websafe. You could encounter spaces in attributes within well-formed XML. I guess what I'm saying is that if space is present then it can't be base64. I understand the need to verify every character though. You are trying to rule out that it can't be base64, I guess.
