<p>Aaron,</p>
<p>thanks for bringing up this issue. Are you planning on
overwriting the original file as you will be overwriting the
original value or will you create a new file? Maybe using links
could help in updating them.</p>

<div>Dear Aaron,</div>
<div> What you are thinking of are called variants. You will
find the CIF style of variants in the imgCIF dictionary. The
NeXus style <br>

<div>which is intended to fill the same role is Mark Koenecke's
proposal in <br>

<div dir="ltr">Hi all, I recall there was a way in NeXus to
mark a group or field in an existing NeXus file as
old/deprecated and add a new one replacing it. For example
if you refined a detector position and you want to remember
what the old position was, but any software reading the file
should use the new position. Can this be done? My googling
on the website didn't find it.
