Configuring response headers

[kellytk]

HTML response hardcodes a text/html content type, however XHTML5 requires[0]:

When a document is transmitted with an XML MIME type, such as application/xhtml+xml, then it is treated as an XML document by Web browsers, to be parsed by an XML processor.

Where please is it documented how that should be configured with axum? If it isn't, modify the response's header in the handler, mostly duplicate HTML response to an XHTML response pull request, other?

I would recommend you duplicate the Html response and customize it to your needs.

You could also write a middleware that looks for responses with an html content type and then change it.
