And, other deprecations can be targeted and marked up. Maybe WikiLint? That could play on the notion that, for most users, wiki = wikitext. -S.

If I open a <nowiki> tag and there's no closing tag, is that an error? What about partial heading syntax (such as "== foo" at the start of a line) or unclosed HTML comments ("<!--")? Is that considered invalid input? Is it an error if I input an anchor element or a script element and it's non-functional in output without any warning message or error text or explanation to the user? Is it an error or at least considered invalid input if there are warnings or even rejection of the edit, in the case of blacklists and abuse filters? Are you just saying that Parsoid will accept most inputs? Surely it has a size limit, so overly large wikitext would likely be some kind of error? MZMcBride
