Retaining @conref as another name in merged middle file

[ToshihikoMakita]

I want retain @conref attribute after preprocess and in the merged middle file with DITA-OT 4.2.4.
One of my users has been using DITA-OT 1.7.5 for a long time. Now they are moving toward to DITA-OT 4.2.4. In DITA-OT 1.7.5, I modified org\dita\dost\writer\DitaWriter.java and saved @conref attribute as @conref_org. This attribute is very important because the user uses this attribute for your document reviewing with PDF.
I have downloaded the newest DITA-OT source code. But I cannot find which Java module I should apply above changes.
Any advices are appreciated!

Hi @ToshihikoMakita

It's been a month since you ask, but you can override dita-ot-4.2.3/plugins/org.dita.base/xsl/preprocess/conrefImpl.xsl to retain @conref attribute.

Create a new plugin to override this attribute and declare the overriding XSL

<plugin id="org.my-plugin-name">
    <feature extension="dita.xsl.conref" file="xsl/conrefImpl.xsl"/>
</plugin>

Create a new XSL from dita-ot-4.2.3/plugins/org.dita.base/xsl/preprocess/conrefImpl.xsl to override templates and save it in this new plugin.

In template <xsl:template match="*[@conref][@conref != ''][not(@conaction)]" priority="10">, add a variable to retain needed information, such as <xsl:variable name="myns:conref-ori" select="substring-after(@conref, '#')" as="xs:string?"/>.

Then, pass this variable to <xsl:template match="*" mode="conref-target">. Call is from <xsl:apply-templates select="$target[1]" mode="conref-target">

Use it when the element is created

<xsl:element name="{$original-element}">
    <xsl:apply-templates select="$original-attributes" mode="original-attributes"/>
    <xsl:for-each select="@* except @id">
        <xsl:if test="not(name() = $source-attributes)">
            <xsl:choose>
                <xsl:when test="name() = 'href'">
                    <xsl:apply-templates select=".">
                        <xsl:with-param name="current-relative-path" tunnel="yes" select="$current-relative-path"/>
                    </xsl:apply-templates>
                </xsl:when>
                <xsl:otherwise>
                    <xsl:apply-templates select=".">
                        <xsl:with-param name="current-relative-path" tunnel="yes" select="$current-relative-path"/>
                    </xsl:apply-templates>
                </xsl:otherwise>
            </xsl:choose>
        </xsl:if>

    </xsl:for-each>

    <!-- HERE -->
    <xsl:attribute name="conref_orgs" select="$myns:conref-ori"/>

    <!-- Continue processing this element as any other -->
    <xsl:apply-templates select="node()">
        <xsl:with-param name="current-relative-path" tunnel="yes" select="$current-relative-path"/>
        <xsl:with-param name="WORKDIR" tunnel="yes" select="$WORKDIR"/>
    </xsl:apply-templates>
</xsl:element>

Hope that help
