This is clearly what I am planning, particularly given I am already 
parsing my content for generating content-editable HTML in WebView.

But not having an official way to do this (for documentation and 
teaching) is a security problem for me. When someone will add 
localization support to its application and load these FXML directly in 
its scenegraph, will it know that localization can create nodes from any 
class resolvable by classloader used by FXMLLoader? (possibly the only 
classloader of its application).

A mitigating solution is OSGi to have more control on the list of 
classes in your classloader (one classloader per module/plugin), but 
Oracle seems to officially dislike torturing classloaders.

I have no problem with the proposed DOM-like rich text API (and internal 
representation); I think this is perfect as an API (not serialized).

My security problem is for the frequent combination of rich text (if it 
is serialized in FXML) with less trusted source of this rich text (like 

An importer from HTML or RTF will clearly solve my problem, particularly 
if advertised (in official documentation) as a secure solution for 
localizable rich text.
