Hi Martin,

I think you want to check out a thread from the TEI council listserv
"date attributes: summary, problems, and some suggestions", which is
publicly available here:

I haven't read through the entire thread, but in the first message Syd
suggests deleting @precision. His argument:

* The precision= attribute is superfluous, as the precision is
  represented in the value of the value=, dur=, notBefore=, notAfter=,
  from=, or to= attribute(s).
  One might argue that we should instead change this attribute to
  indicate that a time is precise only to the minute or hour (as
  opposed to second or fraction thereof) and thus not require our
  extension to W3C datatypes. However, this may become a non-issue
  depending on outcomes of the items discussed below; besides, I
  wouldn't make this argument, so ...
  Suggestion: delete it.

You'll have to go through the thread to see the full discussion, but
it might give you suggestions for replacing it.
