An IIOInvalidTreeException is thrown when an attempt
by an IIOMetadata object to parse a tree of
IIOMetadataNodes fails.  The node that led to the
parsing error may be stored.  As with any parsing error, the actual
error may occur at a different point that that where it is
detected.  The node returned by getOffendingNode
should merely be considered as a clue to the actual nature of the
problem.
