Comment (by ksgeograf):

 This is the next feature I will work on in Maestro (Repo validator).
 This is a potentially endless point, so I will try to keep a list of known
 problems here. Feel free to add any detail that you wan't Maestro to
 detect as either a warning or error.

  *  FeatureSource:
     *  Perform the "Test Connection"
     *  Perform a "Describe Schema"
     *  Perform a "Get Identitie Columns"
     *  Perform a random select.

   *  Layer
     *  Detect missing featuresource, class, geometry or columns.
     *  Detect no scale ranges (warning)
     *  Detect no items visible in a scale range.
     *  Detect scale ranges with gaps eg. [0-10[ [11-20[ (warning)
     *  Try sample rendering, re-test without filter, labels, links or
 tooltips, to detect errors in these.
     *  Try sample rendering with default font and symbols.

   *  Map
     *  Detect that all layers exist, and their permissions are equvalent
 to the map.
     *  Detect that spatial contexts for layers are within the maps.
     *  Warn if coordinate systems are not the same (performance penalty).
     *  Warn (error?) if raster layer is not in the same coordinate system.
     *  Perhaps check for visibility logic, ea. order should be: rasters,
 polygon layers, lines, then points.

   *  Layout
     *  Check that the map exists.
     *  Check that the startup is within the map bounds.

   *  Fusion
     *  Same as layout.
