  \class QVersitDocument
  \preliminary
  \brief The QVersitDocument class is a container for a list of versit properties.
  \ingroup versit

  For example a vCard can be presented as a QVersitDocument that consists of a number of properties
  such as a name (N), a telephone number (TEL) and an email address (EMAIL) to name a few.
  Each of these properties is stored as an instance of a QVersitProperty in a QVersitDocument.

  QVersitDocument supports implicit sharing.
