[tei-council] @source and @version for versioning an ODD

[Kevin Hawkins]

When Sebastian announced P5 1.7.0, he made mention of this change:

  * 2010-05-08 : add new source attribute and revise datatype of
existing version attributes for consistency

It was, as I recall it and as I find in passing reference in another 
SourceForge ticket, designed to allow us to tie an ODD to a particular 
version of P5.

So while both attributes are now included in P5 with brief attribute 
descriptions:

http://www.tei-c.org/release/doc/tei-p5-doc/en/html/ref-att.readFrom.html

http://www.tei-c.org/release/doc/tei-p5-doc/en/html/ref-TEI.html

http://www.tei-c.org/release/doc/tei-p5-doc/en/html/ref-att.translatable.html 
<== By the way, should the datatype be changed to data.version and the 
note revised?

I can't find any documentation on how to use them in an ODD.  I thought 
I would start with the SourceForge ticket that this was implemented, but 
I can't find it through keyword searching of any kind.  Can't even 
figure out how to search either SourceForge by date that a ticket was 
closed or search Subversion by date of commit of a change in order to 
find out more.

Could someone point me in the right direction?

And would someone be willing to write some documentation for P5 on these 
attributes?
