No --- that's documentation for a specific contrib module, not
documentation about the feature in general.  Currently the general
description of dictionaries says that it's impossible for a dictionary
to modify the input lexeme.  Clearly that needs some adjustment,
but I'm not sure what, because the feature is not explained anywhere ;-)
