Hi, I've set up a SourceForge project with the intention of establishing an XML format for crosswords based on the XML format used by Crossword Compiler.http://sourceforge.net/projects/xwcrosswords/
I'm a UK setter and a member of the Mango crossword setting team. The idea is that eventually all crossword software will be able to read and write in XML format. The format will cater for sudoku and other word games, and will allow puzzles to be easily uploaded to Android phones. Please get in touch if you would like to help out. I especially need help with XML and Java programming.
