Alternative label for depth (S0600169)

[dr-shorthair]

The definition of Depth matches what is often called "thickness (vertical)" - maybe add an alternative label?

Thank you for suggestion @dr-shorthair. We have a number of P01 parameters that are still not modelled to the PUV terms and that use "thickness" in the preferred label. We will review the usage of both terms in P01 and decide whether it is safe to have it in the alternative label field.
