The KML 2.0 reference document is now available at code.google.com. The companion document, the KML 2.0 Tutorial is also availble there and is highly recommended reading. It carefully anticipates and answers many of the questions that KML developers will have. Within the Tutorial document is a link to a sample KML file with examples corresponding to the Tutorial's topics.

The documents, like the software itself, are in beta. Improvements, both those we know we want to make and extra ones yet to be suggested, will be made as time passes.

We know you've been waiting for a long time and we thank you for your extended patience.
