get.refentry.metadata.prefs — Gets user preferences for refentry metadata gathering
<xsl:template name="get.refentry.metadata.prefs"/>
The DocBook XSL stylesheets include several user-configurable
    global stylesheet parameters for controlling refentry
    metadata gathering. Those parameters are not read directly by the
    other refentry metadata-gathering
    templates. Instead, they are read only by the
    get.refentry.metadata.prefs template,
    which assembles them into a structure that is then passed to
    the other refentry metadata-gathering
    templates.
So the, get.refentry.metadata.prefs
    template is the only interface to collecting stylesheet parameters for
    controlling refentry metadata gathering.
