Potential Issue -- Computed Standard Names check examines variable(s) examines s_rho

[daltonkell]

In testing this dataset http://tds.eds.ioos.us/thredds/dodsC/ioos/ofs/dbofs/forecast/fields/DBOFS_Forecast_Fields_best.ncd, the Compliance Checker yields a result for the computed_standard_name:

§4.3 Vertical Coordinate
* §4.3.3 The standard_name of `s_rho` must map to the correct computed_standard_name, `{'height_above_mean_sea_level', 'altitude', 'height_above_reference_ellipsoid', 'height_above_geopotential_datum'}`
* §4.3.3 The standard_name of `s_w` must map to the correct computed_standard_name, `{'height_above_mean_sea_level', 'altitude', 'height_above_reference_ellipsoid', 'height_above_geopotential_datum'}`

Both s_rho and s_w are dimensionless vertical coordinates. They each have a formula_terms attribute, and the variables listed there should map to a computed_standard_name, but not s_w or s_rho (see here). As a result, these messages should not appear. @benjwadams could you double check my understanding?
