This spec was named XMLHttpRequest 2 until very recently. As work on XMLHttpRequest 1 was dropped, both specs were merged and the Editor's Draft of XMLHttpRequest 2 already dropped the "2".
One of the key features of XMLHttpRequest is the support for blob/file upload, needed notably for photo apps.
- Determine if there's need to support all of the spec or just the de facto part of the standard which has been implemented in browsers for a while combined with support for uploading blobs.
- Determine support for blob upload support in existing browsers.
