I am still working with a Theme from 2005 (!). I spent now some time to make it compatible for version 12. theme.xml is a part of the .dtl file.
But a few things I find hard to figure out - trial and error. So, a description or dtd would be very helpful. Additionally, because my theme is stone age old and some properties came later. I have 2 specific question.
1: What is for?
2. List of props where I can apply a font.
