Hi! I don’t understand how metadata tags works…  
Does these metadata tags works only in Flex?

Because I have an .as file that compiles in Flash (Astra component from Yahoo!) and inside it there are lines like these:

[Style(name=“closedBranchIcon”, type=“Class”)]

I don’t know…  
I can’t understand that line even…
