* NOTE! If the two nodes aren't in the same connected subtree,

*
* XXX aOffset1 and aOffset2 should be uint32_t since valid offset value is
* between 0 - UINT32_MAX. However, these methods work even with
* negative offset values! E.g., when aOffset1 is -1 and aOffset is 0,
* these methods return -1. Some root callers depend on this behavior.
* On the other hand, nsINode can have ATTRCHILD_ARRAY_MAX_CHILD_COUN
* (0x3FFFFF) at most. Therefore, they can be int32_t for now.
