Erik, The only reason for keeping it internal at this point is resources, having the time to document what has been done thus far in a publishable form. We have also been refining the rules and transformation based on implementation experience which has made this even more difficult. However, we feel that we are very close and are working on the documentation as quickly as we can (given priorities). I understand that you want us to simply publish what we currently have, but this is not the approach that Thomas wants to take at this point. Our intent is to provide a description of the transformation rules, and an XSL transform. The other factor is that the source of this transform is an Operational Template document, which is yet to be stabilised as we are awaiting the next draft of the Template Specification. I suspect that the TDS transformation will be published after this. I will leave it to Thomas to make any further comment on his return from leave.
