Ah. Ok, yes, I was overcomplicating the problem in my head. Now your question makes perfect sense. Thank you for explaining things; I jumped to wrong conclusions early (based on other challenges with namespaces). What you found out is true, of course, but one caveat: if you need to write XML, you do need those namespace declarations for interoperability. The fact that Jackson XML module accepts content using just the local name can be seen both as a feature and a bug. :) (meaning: some users would prefer strict matching to catch potentially incorrect XML) -+ Tatu +- ps. There probably is another feature request in here: it would be "Default XML namespace for Java types" instead of "Default XML namespace within XML document". I'll keep that in mind for the future. > > On Tuesday, July 26, 2022 at 8:59:36 AM UTC-7 Tatu Saloranta wrote: >> >> On Mon, Jul 25, 2022 at 5:43 PM Norbert Kiesel <[email protected]> wrote: >> > >> > What you described seems to be for serializing to XML.
