+* :guilabel:`Fixed Elevation Range`: The raster layer (or selected raster band)
+  is associated with a fixed elevation range.
+  This mode can be used when a layer has a single fixed elevation or a range (slice) of elevation values.
+  If a range is specified, pixels will be extruded over this range.
+  You can set the :guilabel:`Lower` and :guilabel:`Upper`
+  elevation range values for the layer, and specify whether the lower or upper :guilabel:`Limits` are inclusive or exclusive.
+* :guilabel:`Fixed Elevation Range Per Band`: Each band in the raster can have a fixed elevation range
+  associated with it. This is designed for data sources that expose elevation-related data in bands, such as NetCDF files.
+  For example, a raster with temperature data at different ocean depths.
+  When rendering, the uppermost matching band will be selected and used for the layer's data.
+  This feature is exposed as a user-editable table for raster bands with lower and upper values.
+  Users can either populate the lower and upper values manually
+  or use an |expression| :guilabel:`Expression` to auto-fill all band values based on expression.
+  The expression-based fill allows you to design expressions that extract useful information from band names.
