Sorry if this is already answered, but I spent several hours and couldn't find an answer in the archives or documents. Question 1: I want to create a model such that I can have either one or both of a set of elements, but not none. The following model describes my desired result: <xs:choice> <xs:sequence> <xs:element name="StartTime" type="xs:dateTime"/> <xs:element name="StopTime" type="xs:dateTime" minOccurs="0"/> </xs:sequence> <xs:sequence> <xs:element name="StartTime" type="xs:dateTime" minOccurs="0"/> <xs:element name="StopTime" type="xs:dateTime"/> </xs:sequence> </xs:choice> However, this violates the "Unique Particle Attribution", according to the following message: [Error] test.xml:5:79: Error: cos-nonambig: (,StartTime) and (,StartTime) violate the "Unique Particle Attribution" rule. I know this is related, even though the line number is bogus, because I can comment out either of the sequences and the choice and it will not produce this error (but obviously isn't what I want). I have read about a scenario similar to what I want using substitutionGroups, but I can't figure out how the typing would need to be for the head type and the derived type(s). Any suggestions or references? Question 2: How do I get a CDATA like type for an element? What I want is to encapsulate a document as payload in an element in an outer document, and have it be completely opaque. If the payload document happens to be HTML, XML, or anything else, I don't care and don't want parsers or processors to touch it. It's just a blob of element content. For the life of me, I can't figure this out. Any help, pointers? Any pointers or help would be most appreciated! Thanks!
