# IBaseUxmlFactory

> Base interface for UXML factories. While it is not strictly required, concrete factories should derive from the generic class UxmlFactory<TCreatedType, TTraits> or UxmlObjectFactory.

## Definition

* **Type:** Interface
* **Namespace:** [UnityEngine.UIElements](/engine/6000.0/script-reference/unityengine/uielements.md)
* **Assembly:** UnityEngine.UIElementsModule

> **Warning:**
>
> **Deprecated.** IUxmlFactory is deprecated and will be removed. Use UxmlElementAttribute instead.

```csharp
public interface IBaseUxmlFactory
