Wrong place. This section is for the statement types, i.e. the symbol immediately following -- #. ? is a modifier to the argument type, not a statement type.
| - `float` | ||
| - `bool` | ||
| - `timestamp` | ||
| - `list` |

list is not a type. list:{type} is a modifier on other types. You would probably want to change this to list:{type} instead of list.
| ```sql | ||
| -- #{ group.name | ||
| -- # :var_name1 list:int | ||
| -- # :var_name2 list?float |

What does list? mean? Please explain it better.
| - `NOW` | ||
|
|
||
| ###### `list` | ||
| An array of values whose type must be specified in the same way as the variable declaration. |

Where is this allowed? Just reading the documentation, I would expect this to be usable in INSERT INTO tbl (a, b) VALUES (:a, :b) where a and b are lists. But in fact this is only allowed in the IN context.
Furthermore, should it be used as WHERE col IN :list or WHERE col IN (:list)? Please clarify.
| ###### `timestamp` default | ||
| A numeric value that can be parsed by [`(int)` cast, equivalent to `intval`](https://php.net/intval) or [`(float)` cast, equivalent to `floatval`](https://php.net/floatval) | ||

| **Allowed default values:** |

This font doesn't look good in rendered form.
| `true`, `on`, `yes` or `1` will result in true. Other values, as long as there is something, will result default false. (If there is nothing, the variable will not be optional) | ||

Consider restructuring this section entirely. This section is supposed to describe default values, not to describe the types. Since description of the type is required, consider restructuring the section such that each type has its documentation and VAR_DEFAULT doesn't have its own place.
