/*!
  \brief Individual record item contained in the NfcRecordModel.

  The item stores all the data needed to properly draw it on the UI
  using a delegate, as well as to convert it to a piece of information
  in an NDEF record.

  Note that an individual NfcRecordItem doesn't represent a whole
  NDEF record, just one piece of information in it (like the text language
  in a title record in a Smart Poster, or the longitude in a Geo record).

  A valid construct that can be converted to an NDEF record needs to be
  made of at least a single NfcRecordItem of the header record content type,
  with the message type defining the NDEF record it's representing, so that
  the NfcModelToNdef class can properly convert it.

  Typically, at least one other NfcRecordItems follow successively after the
  header, containing the data to be stored in the record (e.g., longitude,
  latitude, title, title language, etc.). All of those NfcRecordItems that
  belong together have to be stored right after each other in the model,
  all with the same message type.

  A header content type is only allowed at the beginning of a record
  definition, afterwards only data NfcRecordItems can follow; another
  header would mean the beginning of another record definition.
