# What each call writes

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 keeps only the attributes its spelling holds, such as a heading's level and a link's target, so a document holding any other loses it even where its row says `holds`: to edit and save back, use `adfToLosslessMarkdown` and `losslessMarkdownToAdf`. An image holding more than the alt, layout, type and url of this page's example, as editor-written ones do, rides the carry element in HTML, where this page shows `<img>`.

`./feature-table/write.sh` writes this page. Don't edit it by hand.
