Good call. Axises should be pretty simple. In my search, I stumbled upon the source in grep code (though I know it is available from openjdk) and spent some time looking at HBox and VBox as they are on the simpler side of things.

You could create a feature request in Jira (https://javafx-jira.kenai.com) for such documentation or email the documentation team (javasedocs_us at oracle.com), or write a blog or a openjfx wiki article (https://wiki.openjdk.java.net/display/OpenJFX/Main) if you work out some good techniques.

Never thought about a ticket for docs. Yeah, I plan to blog once I get feel for things.
