The nearest approximation to Sedna that I know of is DDBI's Sqlite 
layer, which only shares the similarity that it's not through a network.

Using XQuery it looks like you could build a Sedna layer for DDBI, 
though after talking with Lars it sounds like the contract from 
IPreparedStatement is slated to change in the future, so it would be 
more like hitting a moving target.

If you want to see Sedna in D, or more specifically in DDBI, you should 
first create a D port of Sedna, then a D port of the XQuery stuff that 
you would use to translate SQL to Sedna stuff.  By the time you're done 
with all that DDBI might be to a point that it will no longer be such a 
moving target.  I cannot make any certain prediction, but that's what 
I'd wager.

Of interest if you really want to do that is the XML capability spread 
across Tango, Sendero, Mango, Tango Scrapple, and DWin.  I also think 
that Chris E. wrote some XML stuff that would be on his site 
www.dprogramming.com, but I could be mistaken.
