New commit pushed with a spec change and CSR is now in draft mode. Something worth mentioning:

1. I explicitly added "valid UTF8String..." to match the `catch (IOException)` line in the implementation, so if there's anything wrong parsing the value as a string then the byte array will still be there.
2. I feel a little uneasy of the new `if` and `otherwise` words inside parenthesis, especially the second one which seems out of nowhere. Please suggest better wording if possible.
