Question

我用xsd中的一个元素修改了minOccurs = 1，并且没有在ditamap中添加该元素。但是dita运作良好。没有警告，没有错误。该示例是bookmap，它是dita-ot-3.3的形式示例。

xsd：

   <xs:group name="bookmeta.content">
      <xs:sequence>
         <xs:group ref="linktext" minOccurs="1"/>
         <xs:group ref="searchtitle" minOccurs="1"/>
         <xs:group ref="shortdesc" minOccurs="1"/>
         <xs:group ref="author" minOccurs="1" maxOccurs="unbounded"/>
         <xs:group ref="source" minOccurs="1"/>
         <xs:group ref="publisherinformation" minOccurs="1" maxOccurs="unbounded"/>
         <xs:group ref="critdates" minOccurs="1"/>
         <xs:group ref="permissions" minOccurs="1"/>
         <xs:group ref="metadata" minOccurs="1" maxOccurs="unbounded"/>
         <xs:group ref="audience" minOccurs="1" maxOccurs="unbounded"/>
         <xs:group ref="category" minOccurs="1" maxOccurs="unbounded"/>
         <xs:group ref="keywords" minOccurs="1" maxOccurs="unbounded"/>
         <xs:group ref="prodinfo" minOccurs="1" maxOccurs="unbounded"/>
         <xs:group ref="othermeta" minOccurs="1" maxOccurs="unbounded"/>
         <xs:group ref="resourceid" minOccurs="1" maxOccurs="unbounded"/>
         <xs:group ref="ux-window" minOccurs="1" maxOccurs="unbounded"/>
         <xs:group ref="bookid" minOccurs="1"/>
         <xs:group ref="bookchangehistory" minOccurs="1" maxOccurs="unbounded"/>
         <xs:group ref="bookrights" minOccurs="1" maxOccurs="unbounded"/>
         <xs:group ref="data" minOccurs="1" maxOccurs="unbounded"/>
      </xs:sequence>
   </xs:group>

ditamap：

  <bookmeta>
    <author>Howe Tuduit</author>
    <bookid>
      <isbn>071271271X</isbn>
      <booknumber>SG99-9999-00</booknumber>
      <maintainer>
        <organization>Retro Tools</organization>
        <person/>
      </maintainer>
    </bookid>
    <bookrights>
      <copyrfirst>
        <year>2004</year>
      </copyrfirst>
      <copyrlast>
        <year>2007</year>
      </copyrlast>
      <bookowner>
        <organization>Retro Tools, Inc.</organization>
      </bookowner>
    </bookrights>
  </bookmeta>

我认为minOccurs应该起作用。输出将失败。

您必须修改了另一个与DITA-OT参考不同的XSD文件。

如果我修改dita-ot-3.3\plugins\org.oasis-open.dita.v1_3\schema\bookmap\xsd\bookmapMod.xsd进行测试，则DITA-OT构建将失败，并出现以下错误。这是预期的结果。

[bookmapMod.xsd]

        <xs:group ref="linktext" minOccurs="1"/>

        <xs:group ref="shortdesc" minOccurs="1"/>
        <xs:group ref="author" minOccurs="1" maxOccurs="unbounded"/>
        <xs:group ref="source" minOccurs="1"/>
        <xs:group ref="publisherinformation" minOccurs="1" maxOccurs="unbounded"/>
        <xs:group ref="critdates" minOccurs="1"/>
        <xs:group ref="permissions" minOccurs="1"/>
        <xs:group ref="metadata" minOccurs="1" maxOccurs="unbounded"/>

[HTML帮助输出的答案]

我修改 dita-ot-3.3 \ plugins \ org.oasis-open.dita.v1_3 \ schema \ bookmap \ xsd \ bookmapMod.xsd，然后像这样编译：dita -f htmlhelp -i D：\ dita-ot-3.3 \ docsrc \ samples \ taskbook.ditamap -o F：\ Study \ Dita \ output -v。当然，我使用bookmap.xsd而不是DTD修改了任务手册引用。输出仍然很好。没错–

这是因为HTML帮助输出采用了下面介绍的“ preprocess2”：

Map-first preprocessing

如果在dita-ot-3.3 \ plugins \ org.dita.htmlhelp \ build_dita2htmlhelp.xml中将以下行从“ preprocess2”修改为“ preprocess”，您肯定会收到验证错误。

<target name="dita2htmlhelp" unless="noMap" depends="dita2htmlhelp.init,
build-init, use-init.envhhcdir, use-init.hhcdir, preprocess2,
htmlhelp.topics, htmlhelp.copy-image, copy-css">
<antcall target="dita.map.htmlhelp"/>
</target>

minOccurs maxOccurs不适用于dita吗？
