+Units for variables can be designated using symbolic metadata. For more information, please see the [model validation and units](@ref units) section of the docs. Note that `getunit` is not equivalent to `get_unit` - the former is a metadata getter for individual variables (and is provided so the same interface function for `unit` exists like other metadata), while the latter is used to handle more general symbolic expressions.
