/**
 * The data processor interface. It should be implemented by actual data processors.
 *
 * Each data processor implements a certain format of the data. For example, {@glink features/markdown Markdown data processor}
 * will convert the data (a Markdown string) to a {@link module:engine/view/documentfragment~DocumentFragment document fragment} and back.
 *
 * **Note:** While the CKEditor 5 architecture supports changing the data format, in most scenarios we do recommend sticking to
 * the default format which is HTML (supported by the {@link module:engine/dataprocessor/htmldataprocessor~HtmlDataProcessor}).
 * HTML remains [the best standard for rich-text data](https://medium.com/content-uneditable/a-standard-for-rich-text-data-4b3a507af552).
 *
 * And please do remember – using Markdown [does not automatically make your
 * application/website secure](https://github.com/ckeditor/ckeditor5-markdown-gfm/issues/16#issuecomment-375752994).
