下面的schema为撒不起到验证作用，尤其是unique那块？？？

....................................................................
schema代码如下
.....................................................................

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" attributeFormDefault="unqualified">

<xs:simpleType name="ComCEOType">

<xs:selector xpath="Companies/Company"/>
是不是这里应该不用写全路径阿？

写成<xs:selector xpath="."/>

就可以了？因为你上面不是已经定到element为Company了么？

大家讨论

我把schema改了改，也改动了楼上说的地方，
但是还是不可以，重复出现id的时候似乎验证没起作用，顺利通过了

Yeah, I looked at the book, it is a sample, so I think your code is wrong with Attribute unique, I copy this sample of book, I think you will clear~~ =)

<xs:element name="customer">
<xs:complexType>
......
<xs:attribute name="customerID" type="xs:ID"/>
<xs:unique name="uniqueCustomer">
<xs:selector xpath="tc:customer"/>
<xs:field xpath="@customerID"/>
</xs:unique>
......
</xs:complexType>
</xs:element>

pls test your code again
