I've recently finished an updated version of my alternative syntax for xml. This one offers a more Java or C like syntax and other improvements. The project is hosted on java.net at xsltxt.dev.java.net. Here's an example of a simple stylesheet that demonstrates the syntax.

stylesheet 1.0;

output method=text;

// For each row
tpl [/table/row] {
  if [@nullable] {
    nullable(#n = `@name`);
  } else {
    notNullable(#n = `@name`);
  }
}

tpl nullable(#n) {
  $n; " IS NULL;";
}

tpl notNullable(#n) {
  $n; " IS NOT NULL;";
}
