+#### Sepcial case: multiple choice "checkboxes" ####
+
+As a special case, enum arrays with `"uniqueItems": true` can be represented as multiple columns,
+with one column per choice.  The choices are denoted as the last `PATH` component, the column type
+must be `MULTIPLE_CHOICE`.
+
+Stored data is denoted as an "x" character in the respective cell, empty cells denote that the item
+was not selected.  Additionally, the implementation also allows `TRUE` or `1` for selected items,
+and `FALSE`, `0` or cells with only whitespace characters for deselected items:
+
+| `COL_TYPE` | `MULTIPLE_CHOICE` | `MULTIPLE_CHOICE`    | `MULTIPLE_CHOICE` |
+| `PATH`     | `skills`          | `skills`             | `skills`          |
+| `PATH`     | `Planning`        | `Communication`      | `Evaluation`      |
+| `IGNORE`   | skills.Planning   | skills.Communication | skills.Evaluation |
+|------------|-------------------|----------------------|-------------------|
+|            | x                 |                      | X                 |
+|            | `"  "`            | `TRUE`               | `FALSE`           |
+|            | 0                 | x                    | 1                 |

+These rows correspond to:
+
+1. Planning, Evaluation
+2. Communication
+3. Communication, Evaluation
