Documentation of PolyspaceData in report template generator

I'm creating custom Polyspace report template. I saw in default reports PolyspaceData object used multiple times, but I can't find its documentation. Just some unanswered questions on the forum. Does anyone know where to find description of this object (members, functions, examples,...)?

Sample usage in report template:

    ReviewInfo = { PolyspaceData.GetMessage('project'), PolyspaceData.GetProjectName; ...
                   PolyspaceData.GetMessage('version'), PolyspaceData.GetVerifVersions; ...
                   PolyspaceData.GetMessage('projectLeader'), ''; ...
                   PolyspaceData.GetMessage('qualityReviewer'), '' };
