Working with Schema Indicators

Hi everyone, I am new to creating XML schemas and I ran into a problem doing so for an existing XML document. I have one element that (this doesn't compile) looks basically like this: <xs:complexType name="type0"> <xs:someIndicator> <xs:element name="elem0" type="xs:string" minOccurs="1" maxOccurs="1" /> <xs:element name="elem1" type="xs:string" minOccurs="1" maxOccurs="1" /> <xs:element name="elem2" type="xs:string" minOccurs="0" maxOccurs="unbounded" /> </xs:someIndicator> </xs:complexType>As far as indicators go, I only have three options all, sequence and choice: * All will not work because my elem2 maxOccurs attribute is "unbounded". * Sequence won't work because sometimes elem1 precedes elem0. I would change this but the current document I'm working with is 4000 lines long and would take a long long time. * Choice won't work for me either because I need more than 1 element to show up. What I'm basically trying to do is find a way so that for one complexType, have 3 element types as children that can be in any order and one of them can appear an unlimited number of times. Can someone please help me out with this? I would greatly appreciate it. :)

What about using sequence, and creating two different sequences, one when elem0 is before elem1, and another for the other case. Then put those two sequences in a choice, itself in a complexType ?Not clear ? I'll try with an example :

<xs:complexType name="type0">  <xs:choice>   <xs:sequence>    <xs:element name="elem0" type="xs:string" minOccurs="1" maxOccurs="1" />    <xs:element name="elem1" type="xs:string" minOccurs="1" maxOccurs="1" />    <xs:element name="elem2" type="xs:string" minOccurs="0" maxOccurs="unbounded" />   </xs:sequence>   <xs:sequence>    <xs:element name="elem1" type="xs:string" minOccurs="1" maxOccurs="1" />    <xs:element name="elem0" type="xs:string" minOccurs="1" maxOccurs="1" />    <xs:element name="elem2" type="xs:string" minOccurs="0" maxOccurs="unbounded" />   </xs:sequence>  </xs:choice></xs:complexType>
