 The hints can be added before the data format is started (for example when the 
route is configured).
+To remove a hint, such as a default one, use the 'removeFromHintMap' method.
+The maps returned by 'getWriterHintMap' and 'getReaderHintMap' are read-only.
 For possible hints, please consult the xzing documentation.

Review Comment:
   Optional, pre-existing: since this paragraph is being touched, `xzing` could 
become `ZXing` here, and the example just above uses `Boolean.true`, which does 
not compile (`Boolean.TRUE`). The catalog copy under 
`catalog/camel-catalog/src/generated/resources/org/apache/camel/catalog/docs/barcode-dataformat.adoc`
 would need regenerating as well.
