Invisible XML (ixml) is a language and process for identifying structure in documents. Invisible markup allows users to exploit the implicit structures in documents without the need for explicit markup. Since the release of the ixml standard in 2022, we have seen a steady increase in the use of ixml, as well as many interesting conference presentations about the language. The community group felt the time was right for an event exclusively dedicated to invisible markup.
