Using norma to reverse engineer a database which has merge replication enabled is an interesting experience, if somewhat frustrating, with hundreds of otherwise irrelevant object types and their associated roles and constraints dropped in the middle of everything else. (I was trying to use orm in vs 2008.)
Since there seems to be no discussion of this issue on this site, I do not expect any immediate resolutions of this issue. (I might be able to alleviate some of my problems by editing the raw .orm file, but with over a thousand non-adjacent lines to change, that might be error prone.)
However I did want to raise this issue so that hopefully someone could deal with it in the future.
