How to hide procedure/title label and number? "Procedure 1. " And hide in all languages?

[jodekirk]

I can't figure out how to override/remove auto gen procedure title and number text.
I found the closed issue about Section, but that was on pre release, so maybe it doesn't work anymore.

Tried adding to custom.xsl:

<xsl:variable name="v:custom-localizations">
  <locale xmlns="http://docbook.org/ns/docbook/l10n/source"
          language="en"
          english-language-name="English">
    <group name="list-of-titles">
      <template name="procedure">%c</template>
    </group>
    <group name="title-numbered">
      <template name="procedure">%c</template>
    </group>
  </locale>
</xsl:variable>

Error:

I tried using only the example in the documentation to update localizations but I get an error.
https://xsltng.docbook.org/guide/2.1.2/ch-localization#l10n-customization_s2

<xsl:variable name="v:custom-localizations">
  <locale xmlns="http://docbook.org/ns/docbook/l10n/source"

    <mappings>
      <gentext key="TableofContents">Contents</gentext>
    </mappings>
    <group name="title-numbered">
      <template name="appendix">%l%.%c</template>
    </group>
    <group name="xref-number">
      <template name="appendix">App. %l</template>
    </group>
  </locale>
</xsl:variable>

If I remove the <group> tags it works without error, but that's the part I'm trying to customize.

How do I customize this without errors?

<l:template match="self::db:procedure">
  <lt:token key="Procedure"/>
  <lt:text> </lt:text>
  <lt:label/>
  <lt:separator/>
  <lt:content/>
</l:template>

to:

<l:template match="self::db:procedure">
  <lt:content/>
</l:template>

[frankarensmeier]

If you want to remove the title altogether, you can define an empty title page template in the variable v:templates.

Example:

    <xsl:variable name="v:templates" as="document-node()"
        xmlns:v="http://docbook.org/ns/docbook/variables">
        <db:procedure></db:procedure>
    </xsl:variable>

https://xsltng.docbook.org/guide/2.1.2/ch-implementation#header-templates "Title page" templates are actually used for lots (if not all?) formal elements.

Hope this helps.
