Techniques to tag content with arbitrary labels: Tags, Labels, Flags, and Selectors.
Flags are like tags, but without the implicit requirement to document them. Like tags the values of the flags property are used for metadata-tagging.
While tags are typically rendered on the document, flags are not.
Since 2.4.1
Flags are available since version 2.4.1 of the projectdoc Toolbox.
In case you do not need to show your labels or use them for meta-tagging, then choose the naming convention "Selector" for adding additional selectors. In case you need multiple sets of selectors, add a suffix to "Selector" like "Selector Security Issues.
While tags are typically rendered on the document, selectors are not.
