如何在Schematron中将命名空间和路径组合为元素？

Question

我可以正确地验证这个XML文件。

<?xml version='1.0' encoding='UTF-8'?>
<world>
    <dog>
        <ears DIRTY='no'>
        </ears>
    </dog>
    <human>
        <ears EARRING='yes'>
        </ears>
    </human>
</world>

用这个模式

<?xml version="1.0" encoding="UTF-8"?>
<schema xmlns="http://purl.oclc.org/dsdl/schematron">
    <pattern>
        <rule context='world/human/ears'>
            <assert test="@EARRING">ears element in human must have EARRING attribute</assert>
        </rule>
        <rule context='world/dog/ears'>
            <assert test="@DIRTY">ears element in dog must have DIRTY attribute</assert>
        </rule>
    </pattern>
</schema>

但是，当引入默认名称空间时，我无法正确地验证它。

例如，将其作为XML文件：

<?xml version='1.0' encoding='UTF-8'?>
<world xmlns='default-namespace'>
    <dog>
        <ears DIRTY='no'>
        </ears>
    </dog>
    <human>
        <ears EARRING='yes'>
        </ears>
    </human>
</world>

这是一个模式：

<?xml version="1.0" encoding="UTF-8"?>
<schema xmlns="http://purl.oclc.org/dsdl/schematron">
    <ns prefix="mets" uri="default-namespace"/>
    <pattern>
        <rule context='mets:world/human/ears'>
            <assert test="@COLOR">ears element in human must have COLOR attribute</assert>
        </rule>
        <rule context='mets:world/dog/ears'>
            <assert test="@DIRTY">ears element in dog must have DIRTY attribute</assert>
        </rule>
    </pattern>
</schema>

它应该失败(@COLOR缺少)，但它没有。

我做错了什么？

每个元素都需要有名称空间前缀。更改：

<rule context='mets:world/human/ears'>

至：

<rule context='mets:world/mets:human/mets:ears'>
