x2svg

x2svg is a tool to render tree like structures as DTDs graphically.

Todos

This is a list of thing that I would see in x2svg

XML Schema parser (like the DTD parser) (pilhuhn working on it)
Use of arbitrary fonts / font sizes (partially done in 1.0, from a certain size on, the Elementbox would need to be enlarged)
Color selection through properties (partially done in 1.0)
Javascript code to enable folding of subtrees when a SVG is displayed online in the e.g. a web browser
Better font selection when rendering the tree as PDF (should be ok in 1.0)
Creation of content model boxes / element boxes as SVG "def-elements" and use of them by reference instead of adding them several times
