Typically this member should contain an exception characterizing the error in detail.

For example the following exceptions may be used:

::com::sun::star::container::ElementExistException

for duplicate nodes.

::com::sun::star::container::NoSuchElementException

for nodes that are not in the schema.

::com::sun::star::beans::IllegalTypeException

for properties having the wrong or an invalid type.

::com::sun::star::beans::PropertyExistException

for duplicate properties.

::com::sun::star::beans::UnknownPropertyException

for properties that are not in the schema.

::com::sun::star::lang::IllegalArgumentException

for data values (names,attibutes,etc.) that are invalid.

::com::sun::star::lang::IllegalAccessException

for changes that violate access restrictions.

::com::sun::star::lang::NoSupportException

for features that are not supported by the current implementation.

If no more detail information is available, this may be left void.
