ArrayBuffer and ByteArray questions

Hi,

Several specs, like File API and WebGL, use ArrayBuffer, while other spec,
like XMLHttpRequest Level 2, use ByteArray. Should we change to use the same
name all across our specs? Since we define ArrayBuffer in the Typed Arrays
spec (
https://cvs.khronos.org/svn/repos/registry/trunk/public/webgl/doc/spec/TypedArray-spec.html),
should we favor ArrayBuffer?

In addition, can we consider adding ArrayBuffer support to BlobBuilder,
FormData, and XMLHttpRequest.send()?

Thanks,

Jian
