Instead of using node_save, which does not do form validation on fields when saving nodes, is it possible to create form values instead of creating a node and inserting directly via node_save so that the nodes can be validated before being created. For example, this would be useful when creating nodes using FEM when fields are required when created. Sometimes values in the feed may not be valid field data, there should be an option to either use drupal_execute (which would do form validation) or insert feeds without validation.
