DT properties which can have multiple entries need to specify what the entries are and define how many entries there can be. In the case of only a single entry, just 'maxItems: 1' is sufficient. Add the missing entry constraints. These were found with a modified meta-schema. Unfortunately, there are a few cases where the size constraints are not defined such as common bindings, so the meta-schema can't be part of the normal checks.
