嵌入swc时未找到符号的定义

Question

当我从swf嵌入符号“Tile”时，它工作正常，当我尝试从swc嵌入相同的符号时，FlashDebugger会抛出此错误：

Error: definition for symbol 'Tile' not found
[Embed(source="../lib/assets.swc", symbol="Tile", mimeType="application/x-shockwave-flash")]
Error: Unable to transcode ../lib/assets.swc.

1. 为什么要使用swc http://livedocs.adobe.com/flex/3/html/help.html?content=compilers_30.html
2. 导入swc文件的示例：Embedding/importing SWC at compile-time in ActionScript, without setting a library path
3. 根据您对哪一个更好的评论：Flex graphic assets: SWF or SWC?
