The updated version of Braille Formats will state that the Special Symbols page must be done in braille order; no more categories.
As to your second question, the braille did not come through. The symbol for "grave accent alone on page 309 is dots 46, 16 which is not an ampersand...and I could not find a symbol in section 11 of Guidelines for Technical Materials that matched that dot configuration. Please clarify that question.
