-/**
- * Detects use of the `bundle' format and extracts nested resources into their own top level
- * resources. The bundle format looks like this:
- *
- * <!-- res/drawable/bundle.xml -->
- * <animated-vector xmlns:aapt="http://schemas.android.com/aapt">
- * <aapt:attr name="android:drawable">
- * <vector android:width="60dp"
- * android:height="60dp">
- * <path android:name="v"
- * android:fillColor="#000000"
- * android:pathData="M300,70 l 0,-70 70,..." />
- * </vector>
- * </aapt:attr>
- * </animated-vector>
- *
- * When AAPT sees the <aapt:attr> tag, it will extract its single element and its children
- * into a new high-level resource, assigning it a name and ID. Then value of the `name`
- * attribute must be a resource attribute. That resource attribute is inserted into the parent
- * with the reference to the extracted resource as the value.
- *
- * <!-- res/drawable/bundle.xml -->
- * <animated-vector android:drawable="@drawable/bundle_1.xml">
- * </animated-vector>
- *
- * <!-- res/drawable/bundle_1.xml -->
- * <vector android:width="60dp"
- * android:height="60dp">
- * <path android:name="v"
- * android:fillColor="#000000"
- * android:pathData="M300,70 l 0,-70 70,..." />
- * </vector>
