Hello -- I have some questions and comments about the 2001 PR XML Schema. 1) The float and double types do not derive from any base type. I believe they should derive from a common base type which allows unlimited precision as long, int, short derive from decimal. AM>> We tried to do this but were unable to come up with a coherent derivation strategy. 2) It is also unclear if doubles and floats values are allowed to start with an optional "+", plus it also only inderectly states that it is valid to start with an optional "-". AM>> Yes, they can start with + or - 3) Is +INF a valid lexical representation for double and floats? AM>>No, you need to say INF Thanks, David Crowley
