The file contents might be, but a "file" usually has other data than the
bits of its contents, like a file name.

If you have a 32 bit value then the sequence of eight bits starting with
the 3rd would not be called a byte usually.

That does not follow, and it's not true either, you can easily make a
form of storage that aligns on bit boundaries rather than bytes, that
just happens to be unusual currently.

With the exception of the Unicode signature.

This is incompatible with the terminology in the XML specification where
the application is what controls the XML processor, roughly speaking.

An XML processor does not usually inform the application of the bytes in
some file, so this is confusing the relationships here.
