What are the steps kept in mind while designing the Zend_Form?

- The markups are placed in the proper places with each element and with the use of form.

- The markup should be generated for the displaying of the element and in the form as well.

- Inject the values in the element markup with the metadata to design it more effectively.

- The reporting errors need to be kept in check to see the repetitive task that is being done using the code.

- The form solution is being provided to address the actions and other features that need to be addressed.
