Issue in XSD while exchanging the doc in events handling ?

Hi Experts,

I am working  on events where I need to pass some information say data types are  String, List of Strings and document from one process when an event  occured  to another process and use that data in second process.

I am creating  one XSD  while creating the event. But here I know how to create the datatype for string and I have done sample application for String data  and it is working  fine and string value is  coming in second process.

Please  let  me know how to create the XSD for List<String> and document.

Would be great to have some links/guide on exchanging  the data  such as List<String> and Document .

Please  help me ... I need to deliver  by  End of tommorow.

Sample XSD (Am using)

<?

xmlversion="1.0"encoding="UTF-8"?>

<

xs:schemaxmlns:xs="http://www.w3.org/2001/XMLSchema"

elementFormDefault="unqualified"attributeFormDefault="unqualified">

<xs:elementname="users">

<xs:complexType>

<xs:sequence>

<xs:elementname="assigner"type="xs:string"/>

<xs:elementname="assignee"type="xs:string"/>

<xs:elementname="processId"type="xs:integer"/>

</xs:sequence>

</xs:complexType>

</xs:element>

</

xs:schema>

Thanks
