The SubType class¶
The SubType class is an enum which defines SubTypes of Formats.
Not each format has a subtype, In this case the FortmatInfo.subtype value is None.
Some formats like XML have subtypes, eg. SubType.TEIP5, SubType.LIDO or SubType.JSONLD.
The full list(s) of defined subtypes can be found in the formatdetect resources folder.
