The HDMF API provides nearly full support for all features of the HDMF Specification Language version 3.0.0, except for the following:
- Attributes containing multiple references (see #833)
- Certain text and integer values for quantity (see #423, #531)
- Datasets that do not have a data_type_inc/data_type_def and contain either a reference dtype or a compound dtype (see #737)
- Passing dataset dtype and shape from parent data type to child data type (see #320)
