That's not what this section says. Instead, it says that you need to auto-detect UCS-4, UTF-16, UTF-8 from the BOM, or guess them or EBCDIC from the encoding of '<?'. This should be enough to actually parse the encoding declaration. Other non-ASCII-compatible encodings can only be used if declared in an upper-level protocol (such as HTTP). The parser is not expected to try out all encodings it supports.
