  \class QSourceLocation
  \reentrant
  \since 4.4
  \brief The QSourceLocation class identifies a location in a resource by URI, line, and column.
  \ingroup xml-tools

  QSourceLocation is a simple value based class that has three
  properties, uri(), line(), and column(), that, taken together,
  identify a certain point in a resource, e.g., a file or an in-memory
  document.

  line() and column() refer to character counts (not byte counts), and
  they both start from 1, as opposed to 0.

   Construct a QSourceLocation that doesn't identify anything at all.

   For a default constructed QSourceLocation(), isNull() returns \c true.
