Awesome it works ! Thank you ! ( and when converting to XSD it made a proper complexType and created elements of that type. ) ---------------------------------------- David A.

The key to solving this sort of problem with RNG is to let go of the idea that you can only name element patterns. In fact, you can name any kind of pattern: a sequence of two elements, a choice between three attributes, a choice between an element and a sequence of two attributes, all these can have names. What you need here is to name a sequence, and you do that like this: > Address = > element name { xs:string }, > element address1 { xs:string} , > ... Note that there are no braces, which are part of the syntax of an element pattern. > ShippingAddress = element shipAddress { Address } > > BillingAddress = element billAddress { Address } > > > The only difference between shipAddress and billAddress would be the element > name. Just so, since th element patterns have the same named content model. > Is this possible in RNG ? I know I can just duplicate the definitions but > that feels so bad ! It certainly would be. -- Even a refrigerator can conform to the XML John Cowan Infoset, as long as it has a door sticker cowan@c... saying "No information items inside". http://www.ccil.org/~cowan --Eve Maler _______________________________________________________________________ XML-DEV is a publicly archived, unmoderated list hosted by OASIS to support XML implementation and development.
