CURR11 — Description of Exception handling semantics

Summary: Text needs to be added to describe what causes an exception to be raised
for a given interface, when the semantics/preconditions for the interface
have been violated (vs. exceptions specific to a vendor
’s implementation).
e.g. Money.[gs]etValue(), MoneyFormatter.[gs]etFormattingString(), etc. It
appears that most every interface raises (FbcException), but quite often
the text which describes which exceptions can be raised, in terms of
ExceptionType and under what conditions the exception is raised/thrown, has
not been detailed. A detailed pass through the entire FbcCurrency spec
should be conducted with attention paid to each interface and its exception
generating details.
