       These are building blocks for the form library,  defining  fields  that
       can  be  created using the form_fieldtype(3x) functions.  Each provides
       functions for field- and character-validation, according to  the  given
       datatype.
       This holds alphanumeric data.
       This holds alphabetic data.
       This holds an enumerated type.
       This holds a decimal integer.
       This holds an IPv4 internet address, e.g., "127.0.0.1".
       This holds a decimal number, with optional sign and decimal point.
       This holds a regular expression.
       The   TYPE_IPV4   variable  is  an  extension  not  provided  by  older
       implementations of the form library.
