The encoder, indicated by xsi:type="Base64AttributeDecoder", processes SAML attribute values that are base64-encoded UTF-8 by decoding them back into UTF-8.
This decoder has no way to determine whether the underlying data is in fact UTF-8, so it should be used with trusted IdPs only and with caution. If the data is binary, it will be exposed to applications as raw octets up to the first null character in the decoded data.
