  \class AbstractXmlPullProvider
  \brief The AbstractXmlPullProvider class provides a pull-based stream interface for the XPath Data Model.
  \reentrant
  \ingroup xml-tools

  AbstractXmlPullProvider allows a stream of items from the XPath Data Model -- essentially XML --
  to be iterated over. The subclass of AbstractXmlPullProvider provides the events, and the
  user calling next() and so on, consumes them. AbstractXmlPullProvider can be considered
  a forward-only, non-reversible iterator.

  Note that the content the events describes, are not necessarily a well-formed XML document, but
  rather an instance of the XPath Data model, to be specific. For instance, maybe a pull provider
  returns two atomic values, followed by an element tree, and at the end two document nodes.

  If you are subclassing AbstractXmlPullProvider, be careful to correctly implement
  the behaviors, as described for the individual members and events.
