针对XSD的XML验证在Oracle中失败，但在XMLSpy中得到验证

Question

XSD在oracle中注册。使用XMLTYPE.schemavalidate根据注册的XSD验证XML。由于“LSX-00295：字段元素”项目“不是简单类型”，因此API会给出错误信息。但是具有相同XSD的相同XML文件在Altova XMLSpy中得到验证。 不知何故oracle正在给出复杂类型的错误。

匿名脚本是如下：

declare 
lxml XMLTYPE; 
l_err varchar2(4000); 
l_transformxml CLOB:='<?xml version="1.0" encoding="UTF-8"?>

显然架构item定义为与simpleType的元件，这意味着它不能包含属性。

<item index="2">a</item>
