This makes it an easy call -- "throws IOException". APIs should never
declare "throws Exception" except maybe in the earliest stage of coming
up with the exception model. And in this case, "IOException" is how any
code doing I/O will already throw exceptions; no need to for more.
By the way, the names "ByteStream" and "CharacterStream" imply they're
good for writing too. Far preferable to say "InputStream" and "Reader".
I/O in languages other than Java should obey those languages' rules, as
(and when) the SAX models are translated to them.
