\since 4.4
\ingroup xml-tools
\inmodule QtXmlPatterns
Subclassing QAbstractXmlNodeModel can be a significant task, because it
requires implementing several, complex member functions. QSimpleXmlNodeModel
provides default implementations of these member functions that are suitable
for a wide range of node models.
Subclasses of QSimpleXmlNodeModel must be thread-safe.
