    In the features list of this alpha version one can read:

    What does this mean exactly? I have imported one of my custom elements in a new project created with 2023.2.0a9 and it seems to work the same. How are you supposed to create a custom element with this version?

    I imagine that instead of using traits and factories, one can add the UxmlElement attribute to the class and the UxmlAttribute attribute to each property that should be available as an attribute in UXML. It seems very nice. I don't know how drawers work for this yet.

    This is a very very good step forward : the public properties + UxmlFactory + UxmlTraits were hard to grasp, and it was easy to fail making a proper custom VisualElement.

    Stating a property is an UxmlAttribute, via a simple C# attribute, is super clean :)

    You don't have to wait for Unity 2023. You can use UnityMvvmToolkit to get data-binding support, and UnityUxmlGenerator to get attributes support. ;)
