positive.code: 
  All of the properties available when defining a field with manual `schema.xml` edits can be passed via the API. These request attributes are described in detail in the section <<defining-fields.adoc#defining-fields,Defining Fields>>.
  
  For example, to replace the definition of an existing field "sell-by", to make it be of type "date" and to not be stored, you would POST the following request:
  
  [.dynamic-tabs]
  --
  
negative.code: 
  The `delete-field` command removes a field definition from your schema. If the field does not exist in the schema, or if the field is the source or destination of a copy field rule, an error is thrown.
  
  For example, to delete a field named "sell_by", you would POST the following request:
  
  [.dynamic-tabs]
