My suggestion would be to create a MetaDataTablePeekFailedException.
Recoverable or unrecoverable is not something that the thrower can
decide, it is the decision of the catcher. For example
DwAttributeNotFoundException can be used to conclude something about a
die's type. But in another case it can mean that your code is looking
for a bogus attribute or is looking at the wrong die. If your code knows
why the exception is thrown then by all means handle it, print a clean
stack trace free error/warning message or nothing at all. Otherwise let
it float up.
