how about simply 'type' (since we are inside SourceFile, the 'file' feels a bit
redundant to me)

Done.

 
-  final bool isDart;
   Document document;
   String code;
+  String linkedCssContent;

I think I prefer to simply reuse 'code' for this too. Basically if type ==
STYLESHEET, code == the contents. 

Alternatively, we could rename 'code' to 'contents' or start using subclasses
for source file.

Done.
