Re: ForCES model xml schema boolean type defition error

Yes,I also think that it's very strange to have three synonyms for that.Is 
there an alias mechanism in schema so that we could define one base boolean 
type and use alias to reflect all the other forms,if there is not then i 
prefer to make things easy to take one of 1) to 3) representation.
