my comment is mostly about the role of the low level API, which is mostly
tricky with setting. Reading Werners answer to my question
"In my understanding the API specification defines the functions for
accessing all our properties, i.e. the input/output parameters and the
expected behaviour. This does not include the specification of how to
parse/write a certain format. All we specify should be format independent."
We will not deal with low level API problems, no matter if related to
getting or setting. The issues you describe about setting are probably
occuring a step before actually trying to set the (new) metadata in a file,
like "what data type should be set if the target format allows for more than
the corresponding ma: property?".
