xdp文件变大问题

今天留意到我这几天正编辑的xdp文件已经到了8MB了，原来不过仅仅几百KB。这又让我想到经常代码写进去后在design view下看不到，只有在xml source界面下才能看到，并且是重复的。

网上google的结果是，这是Livecycle Designer ES 8.2的一个Bug造成的。
A bug introduced with LiveCycle Designer ES Update 1 (8.2) is now fixed in LiveCycle service pack 2 and the Acrobat 9.1 update. The bug causes a processing instruction ex. <?templateDesigner StyleID aped3?> to get copied repeatedly while working with the form. This can lead to extremely large file sizes and sometime causes crashes. The fix removes duplicate StyleID's found in existing forms and prevents them from being created.
