In some applications we see the associated namespace is stripped completely.

➜  2972 aapt2 dump xmltree base.apk --file AndroidManifest.xml

The fix here in theory is easy - resolve resourceId and if you know its a manifest attribute - use it. However that would require us to track all manifest attributes much like android.R.attr.

So this first approach will use any system resource only if the manifest prefix resolved to nothing. This seems safe because we won't touch internal resources or private.
