Is mxml natively supported by flash?

I开发者_如何学编程'm now using the cairngorm flex framework,and it supports mxml .

Is this supported natively by flash or only supported by frameworks?

No, MXML is not natively supported in Flash. The Flex SDK includes a compiler, mxmlc.exe, which converts MXML into ActionScript classes. Adobe Flash CS* does not include this compiler, nor does it contain many of the ActionScript classes that MXML gets converted to.
