Hi,
I need rewrite som DTD into XML Schema. I have problem with one part. In element "item" there may be three combinations of waiting/passing elements: one waiting, one passing, or both. In DTD it is easy and it works: <!ELEMENT item (risid,(waiting|passing|(waiting,passing)))> In Scheme it is easy, but it does not work: <xsd:element name="item"> <xsd:complexType> <xsd:sequence> <xsd:element ref="risid"/> <xsd:choice> <xsd:element ref="waiting"/> <xsd:element ref="passing"/> <xsd:sequence> <xsd:element ref="waiting"/> <xsd:element ref="passing"/> </xsd:sequence> </xsd:choice> </xsd:sequence> </xsd:complexType> </xsd:element> :0,0: Complex type 'C0' violates the Unique Particle Attribution rule in its components 'waiting' and 'waiting' It is possible to write corresponding schema? Thanks for your solutions. Stano.
