Probably need more information that this.   What element is being 'removed' from
a normal acceleration measurement? What are units after application of offset and
scale?  Can cross refer to the in_accel_x_raw for that info if you like.  

OK.  So, may I just state something like "As per in_accel_X_raw
attributes, but minus the gravity acceleration"  ?

Yup, something along those lines.

Wow, I had a lot of typos in my email. :)

Also, but them immediately after the block with the in_accel_x_raw etc  

OK

The organization fo that file needs a rethink but let us try to avoid making
it worse in the meeantime!
