This control is set by the projectdoc Toolbox on document properties imported from other projectdoc documents by the use of the the Document Properties Supplier From Documents Macro, but overridden by a local property with the same name. The control unsupplied marks the property as usually being supplied by an import, but actually the supplied status being revoked since it is overridden by a local property.

Typically this is an internal marker and not used in documentation work. However, this control is exported via the Web API and therefore part of the projectdoc Toolbox API.

In case the importing macro has an identifier, this identifier is provided with an additional control. For instance if the identifier is config, the additional control is named unsupplied:config.

Note that imported properties are automatically importable by other documents.
