Hi Ralph, You can't do conditional type assignment with XSD 1.0. The upcoming XSD 1.1 will allow conditional type assignment but that is still work in progress. The closest you can get in XSD 1.0 is to put the conditionality into an xs:choice of possible elements so you have: <aTypeOneElement> <ONEelement /> </aTypeOneElement> <aTypeTwoElement> <TWOelement /> </aTypeTwoElement> Or define a type that is allows both ONEElement and TWO element and check the constraint at the application level. HTH, Pete Cordell Codalogic Ltd Interface XML to C++ the easy way using XML C++ data binding to convert XSD schemas to C++ classes.
