  \class QVersitDocument

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

  \ingroup versit

  A vCard is represented in abstract form as a QVersitDocument that consists of a number of

  properties such as a name (N), a telephone number (TEL) and an email address (EMAIL), for

  instance.  Each of these properties is stored as an instance of a QVersitProperty in a

  QVersitDocument.

  In addition to the list of properties, QVersitDocument also records the type of the Versit

  document via the VersitType field.  This enum describes the format in which the document is to be

  serialized by QVersitWriter (or the format from which it was read by QVersitReader), and should

  not be used to infer any semantics about the document data.

  QVersitDocument supports implicit sharing.

  \sa QVersitProperty
