Hi! Is it possible to construct simple datatypes by composing other simple data types? Here's a practical example for better understanding: If you define a schema you often have elements or attributes with data like email address, host name, URL, ... All of these data types have to be defined completely from scratch every time (at least I didn't find a better solution) in the Schema. But it would be much cleaner, if I could define the basic data types 'hostname', 'path', 'username', ... Then I specify and email address by composing it of an username'@'hostname. The same for an URL which is protocol'://'hostname':'port and path. If this is not possible with XML Schema Version 1.0 then I'd propose to take the requirement up for Version 1.1. Comments are welcome ;-) Bye, Andreas Hochsteger
