I have implemented simple versioning for FXML documents in FXMLLoader, but without support in tools it won't be very useful. I have agreed with NetBeans and Scene Builder folks that they will include support for versioning too. Support means that they will produce document with two XML namespaces - one defines version of fx: prefixed elements and attributes (xmlns:fx; it's already there, just the version is appended) and the other of actual JavaFX API used to produce document (xmlns; default, no prefix). The first will be checked, because wrong version can cause failure. The latter is only informational, no strict checking of version is possible, but tools can suggest to upgrade runtime, translate document etc.
JavaFX API version is stored in System Properties as "javafx.version". The open question is still where and how to store fxml version in code. I think that we could have also property for this purpose, e.g. "fxml.version" in System Properties. So far it's part of FXMLLoader API, which is probably not very fortunate. What do you think?
