wpf - VisualCollection and ContentPropertyAttribute in XAML -

I want to write a custom framework element that hosts the visuals. My first attempt was to create an example of ContainerVision and write a Cover property for ContainerVision. Children and then set it as ContentProperty so that I can make a visual through XAML. But visual collection only implements iClust or iiList or any supported interface and visual code is not celidated, so I can not apply myself to ILIL.

How can I add host visitors and declarations using them using XAML?

OK, long time ago, but I got this solution back at that time ...

and the controls you can use in XAML
