xjb绑定文件的XML命名空间问题

Question

我有下面的文件：

<?xml version="1.0" encoding="UTF-8"?>
<bindings xmlns="http://java.sun.com/xml/ns/jaxb" 
          xmlns:xs="http://www.w3.org/2001/XMLSchema" 
          targetNamespace="http://java.sun.com/xml/ns/jaxb"
          version="2.1">
    <bindings xs:schemaLocation="Inbound.wsdl#wsdl:types" node="/schema">
        <bindings node="//complexType[@name='TradeIdWithRef']">
            <bindings node=".//attribute[@name='_value']">
                <property name="ValueAttribute"/>
            </bindings>
        </bindings>
        <bindings node="//complexType[@name='Bank']">
            <bindings node=".//attribute[@name='_value']">
                <property name="ValueAttribute"/>
            </bindings>
        </bindings>
        <bindings node="//complexType[@name='Bid']">
            <bindings node=".//attribute[@name='_value']">
                <property name="ValueAttribute"/>
            </bindings>
        </bindings>
        <bindings node="//complexType[@name='addMarketExRequest']">
            <bindings node=".//attribute[@name='_value']">
                <property name="ValueAttribute"/>
            </bindings>
        </bindings>
        <bindings node="//complexType[@name='Offer']">
            <bindings node=".//attribute[@name='_value']">
                <property name="ValueAttribute"/>
            </bindings>
        </bindings>
        <bindings node="//complexType[@name='Price']">
            <bindings node=".//attribute[@name='_value']">
                <property name="ValueAttribute"/>
            </bindings>
        </bindings>
        <bindings node="//complexType[@name='Delta']">
            <bindings node=".//attribute[@name='_value']">
                <property name="ValueAttribute"/>
            </bindings>
        </bindings>
    </bindings>
</bindings>

但是，在xml验证时总是会出现以下错误：

cvc-elt.1: Cannot find the declaration of element 'bindings'. [5]

有人能帮忙吗？

schemaLocation属性必须包含模式的名称空间和到模式定义文件，separated by whitespace的路径。

而且，我不确定这是一个错误，但我不知道为什么要在子节点而不是根节点上声明schemaLocation。
