It's not clear to me that appinfo is considered part of the element declaration - in your example it contained a lookup table that the schema processor wouldn't know anything about. I've always assumed that appinfo was outside of the schema-known information about the element. I can understand an argument that it should be included, but I haven't found anything so far that actually says so. Do you think that's one of these things that's understood and agreend upon but not (yet) spelled out? Cheers, Tom P
