  Content Model: ((title, subtitle?)?, docinfo?, decoration?,
  %structure.model;)

  Attributes:    The document element contains only the common attributes: ids,
  names, dupnames, source, and classes.

  Depending on the source of the data and the stage of processing, the 
  "document" may not initially contain a "title". A document title is not 
  directly representable in reStructuredText. Instead, a lone top-level section
  may have its title promoted to become the document title, and similarly for a
  lone second-level (sub)section's title to become the document subtitle. The 
  "docinfo" may be transformed from an initial field_list, and "decoration" is 
  usually constructed programmatically.

      start contains the ordinal value of the first item in the list, in

  "upperroman" (I, II, III, IV, ..., MMMMCMXCIX [4999]).
      prefix stores the formatting characters used before the enumerator. In 
  documents originating from reStructuredText data, it will contain either "" 
  (empty string) or "(" (left parenthesis). It may or may not affect
  processing.
      suffix stores the formatting characters used after the enumerator. In 
  documents originating from reStructuredText data, it will contain either "." 
  (period) or ")" (right parenthesis). Depending on the capabilities of the 
  output format, this attribute may or may not affect processing.
      start contains the ordinal value of the first item in the list, in 
  decimal. For lists beginning at value 1 ("1", "a", "A", "i", or "I"), this 
  attribute may be omitted.
