<history>
<![CDATA[
Paris was founded in the 3rd century BC by a Celtic people called the Parisii,
who gave the city its name. By the 12th century, it was the largest city in the western world,
a prosperous trading centre, and the home of the University of Paris, one of the oldest universities in history.
By the 17th century Paris was one of Europe's major centres of finance, commerce, fashion, science, and the arts, and it retains that position still today.

答案 0 :(得分：0)
你显然会从一些basic reading on namespaces in XSD中受益。您需要解决的众多问题包括：
xsi，通常用于
http://www.w3.org/2001/XMLSchema-instance，用于XSD名称空间
字首;请改用xs或xsd。xs:import/@schemaLocation是XSD的URL，而不是namespace-URI
对noNamespaceSchemaLocation
你的XSD。看到
