The root level <ReservedTemplateTags> section contains all nodes in the Custom_ReservedTags.xml schema file. Each inner node takes the name of a template .xml node that the rule manager should never delete. The value of each inner node dictates the path to that node in the template file, as the following example shows.
<ReservedTemplateTags>
<annotationParameters>
label/content/contentModuleSettings/
annotationParameters
</annotationParameters>
</ReservedTemplateTags>
The beginning and ending node names, as well as the leaf node name in the path, must match for every child node of <ReservedTemplateTags>.
