It can contain space (%x20) but not tab, carriage return, linefeed, form feed, vertical tab, backspace, delete (or any other control characters).

Hey OAuth group, While I though I knew this, I was looking closely at the OAuth 2.0 spec and read that valid values of the client_id are specified as: VSCHAR = %x20-7E client-id = *VSCHAR This means that the client-id may also contain whitespace characters. Do I get that right?
