需求描述：我们的需求是在输入的xml文档中寻找目标为PubTbl且具有伪属性@rth的处理指令。这些处理指令特定于 Arbortext Editor，它们以表格形式呈现在整个 XML 文档中。
<?PubTbl row rht="0.76in"?>
我们注意到，在我们的 xml 文档中的处理指令中，我们的 ISO Schematron 模式（如下所述）没有被触发。
- ISO Schematron 不验证处理指令吗？
- 如果 ISO Schematron 验证了处理指令，我需要注意任何设置/参数更改吗？
ISO Schematron 模式
<?xml version="1.0" encoding="UTF-8"?>
<schema xmlns="http://purl.oclc.org/dsdl/schematron" id="vert-space-tables_schema"
queryBinding="xslt2" schemaVersion="iso">
<title>Forcing vertical space in content within tables</title>
<pattern id="vert-space-tables_pattern">
<title>Forcing vertical space in content within tables</title>
<rule id="vert-space-tables_processing-inst_rule" context="processing-instruction('PubTbl')"
abstract="false">
<report test="contains(.,'rht=')">
The table have got processing instructions you are looking altered to modify
pagination. </report>
</rule>
</pattern>
</schema>
我正在使用附加的“ant-schematron-2010-04-14.jar”zip 文件中的 ISO schematron 样式表，使用 ant 任务
<taskdef name="schematron" classname="com.schematron.ant.SchematronTask"
classpath="${lib}/ant-schematron-2010-04-14.jar; ${lib}/resolver.jar"/>
<schematron schema="${schema}/vert-space-tables/vert-space-tables.sch" failonerror="false"
queryLanguageBinding="xslt2" format="svrl" OutputDir="${dist}/vert-space-tables"
outputFilename="fail.xml" debugMode="true" failOnError="false" diagnose="true" classpathref="saxon-loc">
<fileset dir="${xml}/vert-space-tables" includes="Forcing_vertical_space_in_content_within_tables-fail.xml"/>
</schematron>
“debug.xslt”——还附加了从 ISO schematron 生成并针对 xml 文档进行验证的 XSL 样式表。
在 debug.xslt 中（在文件的底部），我注意到 apply-templates 只处理元素节点，它永远不会处理处理指令，这是为什么呢？
<xsl:template match="@*|node()" priority="-2" mode="M1">
<xsl:apply-templates select="*****" mode="M1"/>
</xsl:template>
debug.xslt 内容如下：
