Like Tags the document property Flags also supports labelling documents, but without the need to document them.
Flags allow to label documents, but without the need to provide documentation for them. While there is typically a Tag document for each property value element of the Tags property, the flags set to the Flags property do not need to have such a document.
Available since projectdoc version 2.4.1.
Like the Tags' value, the Flags value will be take into account for meta-tagging the document.
For further information, please refer to the Tagging Documents.
