Do not display information within a resource's front matter element of a bookmap with a processing-role="resource-only" attribute on it.
<frontmatter> <topicref href="GUID-4C25FB31-713F-46FF-8EF3-3305CB7D304B" type="subjectScheme" format="ditamap" processing-role="resource-only"> <topicmeta> <!--Navtitle attribute converted into element by SDL Trisoft "Dita11ToDita12.xsl".--> <navtitle>Subject Scheme</navtitle> </topicmeta> </topicref> </frontmatter> I have a resource in the front matter element of a bookmap with a processing-role="resource-only" attribute on it. This means that the information is not to show up in published output. The information does not show up in PDF, so it should not display in Review Space.
