Rose::HTML::Form::Field::PhoneNumber::US::Split - Compound field for US phone numbers with separate fields for area code, exchange, and number.

Rose::HTML::Form::Field::PhoneNumber::US::Split is a compound field that contains three separate text fields for US phone numbers: one each for area code, exchange, and number. It inherits from both Rose::HTML::Form::Field::PhoneNumber::US and Rose::HTML::Form::Field::Compound. It overrides the following methods: build_field(), coalesce_value(), decompose_value(), html_field(), and xhtml_field().
This is a good example of a compound field that combines separate fields into a single value through simple concatenation (plus a separator character). By inheriting from Rose::HTML::Form::Field::PhoneNumber::US, it gets the validation and inflate/deflate features "for free", leaving it to concentrate on the coalesce/decompose features and the building and printing of the separate fields that make up the compound field.
It is important that this class inherits from Rose::HTML::Form::Field::Compound. See the Rose::HTML::Form::Field::Compound documentation for more information.
Other examples of custom fields:
A text field that only accepts valid email addresses.
Uses inflate/deflate to coerce input into a fixed format.
Uses inflate/deflate to convert input to a DateTime object.
A compound field whose internal value consists of more than one object.
A compound field that uses inflate/deflate convert input from multiple subfields into a DateTime object.
A compound field that includes other compound fields and uses inflate/deflate convert input from multiple subfields into a DateTime object.
