Can dimensions have data types?

[Variables,](https://vscode.dev/github/sdmx-twg/wp-sdmx-dpm/blob/main/docs/models-relationships/02_data_definition/02_high_level_mapping_summary.md#L16-L17)

I understood from the previous chapter that properties can be used as keys or facts. This allows to have data types also for dimensions. It would be also essential for non-enumerated categories.
