This message seems to be backward. It simply duplicates [[MediaWiki:Rest-endpoint-desc-post-transform-wikitext-to-html-title-revision/en]]. However, the part 'html-to-wikitext' in the title, as well as the general context, suggest that this message should be about converting HTML to wikitext and not about converting wikitext to HTML.
