-- 为何一个有效？一个无效？
对应于一个相同的XSD，我先写了如下XML：
<?xml version="1.0"?>
<movies xmlns="http://192.168.7.219/movies.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://192.168.7.219/movies.xsd D:\movies.xsd">
<movie type="comedy" rating="PG" review="5" year="1997">
<title>Raising Arizona</title>
<writer>Ethan Coen</writer>
<producer>Ethan Coen</producer>
<director>Joel Coen</director>
<actor>Nicolas Cage</actor>
<comments>A classic</comments>
</movie>
</movies>
它说在movies中的movie位置期待元素movie??!!
后来把名字空间进行了一下限制：
<?xml version="1.0"?>
<film:movies xmlns:film="http://192.168.7.219/movies.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://192.168.7.219/movies.xsd D:\movies.xsd">
<movie film:type="comedy" film:rating="PG" film:review="5" film:year="1997">
<title>Raising Arizona</title>
<writer>Ethan Coen</writer>
<producer>Ethan Coen</producer>
<director>Joel Coen</director>
<actor>Nicolas Cage</actor>
<comments>A classic</comments>
</movie>
</film:movies>
正常验证通过
我不能体会这两者之间有多大区别，望高手指教？
