| 6. If F contains "u", let BMP be false; else let BMP be true. |
| 7. If BMP is true, then |
| a. Parse P using the grammars in 21.2.1 and interpreting each of its |
| 16-bit elements as a Unicode BMP code point. UTF-16 decoding is not |
| applied to the elements. The goal symbol for the parse is Pattern. |
| Throw a SyntaxError exception if P did not conform to the grammar, if |
| any elements of P were not matched by the parse, or if any Early |
| Error conditions exist. |
