I am confused what the "this" is in the attached message?  We have no 
charter to only produce sounds and complete - we do have a charter to 
be compatible with RDF.  What we have tried hard to do is maximize

who said anything about a DAML+OIL => DL converter?  If someone wants 
to write one, I will be happy to discuss it in the implementation 
report, and it would be a nice service to offer.  The current 
converter only translates what is there -- it will guarantee legal 
OWL output, not necessarily Lite or DL.

great, work, thanks to you both.  I will be sure to discuss this in 
the implementation report.  Dan and I also planning to create links 
to more of these things, but not until after we move to LC.

I assume you are letting the appropriate folks know what needs to be fixed.
