Well, in fact semi-structured data  in XML world is common term 
referring to XML documents having sort of variant and flexible 
substructure (usually traditional text documents, such as books or 
articles) whose content model can be described using complex union 
types, xs:choice's, & connectors, xs:any etc. Unstructured data in XML 
terms is probably DTD/Schema-less documents.
