Everything needed to run a comprehensive dev environment. Just type X_ and pick a service from autocomplete; new dev modules will be added as they are built. The only dev service not included in the uber jar is xapi-dev-maven, as it includes all runtime dependencies of maven, adding ~4 seconds to build time, and 6 megabytes to the final output jar size (without xapi-dev-maven, it's ~1MB).
The newest version!

/**
  * This chapter describes the DOM Event Model. The Event interface itself is described, as well as the interfaces for event registration on nodes in the DOM, and event listeners, and several longer examples that show how the various event interfaces relate to one another.
There is an excellent diagram that clearly explains the three phases of event flow through the DOM in the DOM Level 3 Events draft.
