In a text that combines left-to-right and right-to-left segments, these are ordered according to the main direction in use (see The IlvLayoutDirection Attribute). In a segment that contains several words, these can be oriented according to either their own direction or to the main direction (if they differ). This order is specified by the IlvWordBreak attribute.

In Rogue Wave Views Bidi for Windows, this attribute is not supported; only the IlvWordBreakOff value is handled.
