Using Fluid.Controls 1.0 and 1.1 together? [question]

[luntik2012]

If I add some MyItem 1.1 MyItem.qml to qmldir, I can change IMPORT_VERSION = 1.0 to IMPORT_VERSION = 1.1 in controls.pro to use it. But qmldir doesn't contain 1.1 versions of all items, so how could I use new items with all items?
Should I copy all 1.0 items to 1.1 section or there is another solution?
Also how to use Utils and DateUtils when importing 1.1 version? Singletons was registered for version 1.0 only. Is it necessary to register them for 1.1 too or better import both Fluid.Controls versions in qml?

When your program imports version 1.1 of a component that is not register for such version, the QML engine will import the closest version. In this case 1.0.
