* @defgroup addressfield_format Address format API
* @{
* API for generating address forms and display formats.
*
* Addresses forms and display formats are collaboratively generated by one or
* more format handler plugins. An address with a name and a company, for example,
* will be generated by three handlers:
* - 'address' that will generate the country, locality, street blocks
* - 'organisation' that will add the organisation block to the address
* - 'name-full' that will add a first name and last name block to the address
*
* A format handler is a CTools plugin of type 'addressfield' / 'format'. Each
* handler is passed the format in turn, and can add to or modify the format.
*
* The format itself is a renderable array stub. This stub will be transformed
* into either a Form API array suitable for use as part of a form or into a
* renderable array suitable for use with drupal_render(). The following
* modifications are done:
* - when rendering as a form, every element which name (its key in the array)
* is a valid addressfield column (see addressfield_field_schema()), will
* be transformed into a form element, either using a type explicitly
* defined in '#widget_type' or using 'select' if '#options' is set or
* 'textfield' if it is not. In addition, the '#default_value' of every
* field will be populated from the address being edited.
* - when rendering as a formatter, every element which name (its key in the array)
* is a valid addressfield column (see addressfield_field_schema()), will
* be transformed into a renderable element, either using a type explicitly
* defined in '#render_type' or else using 'addressfield_container'. When
* the type is 'addressfield_container' the element will be rendered as
* an HTML element set by '#tag' (default: span).
