You really need to search the forum on this one. This has been a (perceived) weakness of EA's approach to XSD for some time.
Try importing a well-formed XSD schema that includes such an annotation into EA. It can be enlightening, but I don't think you'll be any happier afterwards.
So, make a feature request to Sparx. This has been done before, but it clearly has not yet reached critical mass. More requests might serve to convince the Sparxians that the time has come to address this.
