This is making me a little crazy. I have the following in an mxml file:

  <mx:Image source="img/{XML(data).foo}{XML(data).bar}.png" height="21" width="21"/>

foo and bar are tags defined in my xml file.

What the heck is "XML(data)"? Is it a function or a notation or something else? I've been trying to google it but searching on: flex "XML(" gives me all kinds of stuff I don't want.

is there an alternate name for whatever this is?

如果没有任何其他信息或上下文，我会说该片段的目的是将通用对象（数据）类型转换为完全限定的 XML 类。
