Hi, I believe the error you are getting is not a serious one. I too got the same erro when I tried to validate my schema using XSV. The reason I found out was that when the first 'waiting' is encountered, the parser doesn't know if it is the waiting belonging to the item having 1 waiting or the item having '1 waiting and 1 passing'. This is only a problem with certain parsers while other parsers that implement some form of look-ahead should validate this document fine. BTW, have you tried any DTD to schema converter tools to see what result they gave. Regards, Omprakash.V <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> Stano Paska <paska@xxxxxx To: xsl-list@xxxxxxxxxxxxxxxxxxxxxx k> cc: (bcc: omprakash.v/Polaris) Subject: [xsl] DTD to Scheme 02/02/2005 10:53 AM Please respond to xsl-list 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.
