[DFDL-WG] bit order - proposed new erratum - response to public comment 43, action item 234

[Steve Hanson]

I thought this was as simple as reversing the order of the bits in a byte 
as each byte is read/written?  If not then I have not understood what it 
is doing.

Reading through, my overall comment is that most readers will struggle to 
understand what this property is trying to achieve. It needs to be more 
accessible.

I'm limiting my comments to the below for now, until I get my head round 
what this property is doing. 

"Determines the way that the positions of bits within a byte of data are 
interpreted for content that occupies only part of a byte, or which spans 
from part of one byte to part of another."  I was expecting this just to 
say "Determines the way that the positions of bits within a byte of data 
are interpreted". 

The description needs to say when the property applies. It is not just 
when byteOrder applies, so I think it is to all schema components (ie, 
anything that can potentially have a representation in the data).

Attached is a MS-Word document containing my first cut at an errata to 
describe adding a new bitOrder property to DFDL.

It is more complicated than I would like.
