It may be true that it's not intended to be described as MXML, but it does work, since you can't add sprites directly to containers like panels, you have to add them to UIComponents first, I used a UIComponent MXML tag elsewhere in my app to add a Sprite and it worked just fine. So I don't think that's it. I could declare the UIComponent with AS too, I just used MXML to get my example up and running quickly.
Any other ideas?

(This isn't the actual code in my app, I just isolated a problem and made the problem reproducible it here. In my real app, it's failing to embed an image into a class that is added to a UI component. The class extends Sprite). > The first Image class instance declared with MXML embeds the image just fine. The second, using a UIComponent and adding an instance of the image class to it fails. Why?
