Using The Vex Xml Editor

As an alternative to the closed-source XML Editor we have been using earlier, there is now a tool named VEX based on Eclipse.

Using Vex, one can edit the xml tree in a visually clean way, using CSS to style each element as wanted.

Documentation can be found here.

The Vex plugin for Eclipse seems to still be under slow development (last commit was in 2016), but there are bugs, and so far the user experience has been less than great. It could be worth investigating - it is the only open-source, CSS-styled Xml editor out there, and it is also cross-platform. If desirable, we could add some man power to the project, to get it up to speed and to fit our needs.
