 Each section sets a sample ADF document beside what each call writes for it, then reads that output back: `adfToLosslessMarkdown` with `losslessMarkdownToAdf`, `adfToPortableMarkdown` with `portableMarkdownToAdf`, `adfToHtml` with `htmlToAdf`. `holds` means the reader gives the same document, `loses` a different one, and `refused` that the writer or reader returned an error, whose code the section names.
 
-A result covers that example alone, and the examples are plain. Portable markdown drops every attribute, so a document holding one loses it even where its row says `holds`: to edit and save back, use `adfToLosslessMarkdown` and `losslessMarkdownToAdf`. An image holding an attribute, as editor-written ones do, rides the carry element in HTML, where this page shows `<img>`.
