If your language has other features beyond those that can be defined elsewhere in this questionnaire, you can define those features here. For example, if your language has merged features (e.g. pernum instead of person and number, gendnum instead of gender and number), they can be defined below.

For each feature, you will define a type hierarchy, which consists of a root type you will name (e.g. pernum), and then a series of other values of the feature, each of which is the subtype of at least one of the other values, possibly the root.
