Adobe AIR ignores Android uses-sdk in the manifest

We're trying to set the uses-sdk setting on the Android Manifest. But Adobe AIR seems to be ignoring this and not copying it over. I have other custom items in the manifest, and they are being copied over. What am I doing wrong?

I've tried:

<uses-sdk android:minSdkVersion="8" android:targetSdkVersion="10" />

And this, which is straight from the docs: http://help.adobe.com/en_US/air/build/WSfffb011ac560372f-5d0f4f25128cc9cd0cb-7ffc.html

<uses-sdk android:minSdkVersion="8"></uses-sdk>

Our app descriptor looks like this. The uses-configuration gets included in the output manifest, but the uses-sdk is completely missing.
