 * Make sure all new `.java` files to have a simple Javadoc class comment with at least an `@author` tag identifying you, and preferably at least a paragraph on what the class is for.
 * Add the ASF license header comment to all new `.java` files (copy from existing files in the project)
 * Add yourself as an `@author` to the .java files that you modify substantially (more than cosmetic changes).
 * Add some Javadocs and, if you change the namespace, some XSD doc elements.
 * A few unit tests would help a lot as well -- someone has to do it.
 * If no-one else is using your branch, please rebase it against the current master (or other target branch in the main project).
-* When writing a commit message please follow http://tbaggery.com/2008/04/19/a-note-about-git-commit-messages.html[these conventions], if you are fixing an existing issue please add `Fixes gh-XXXX` at the end of the commit message (where XXXX is the issue number).
