Henry -- Thanks for taking on this huge cleanup task!  A couple of
comments below.

I agree.  A "JDK" prefix on every version number would be redundant.

These secondary version numbers aren't always for standards as such, and
in some cases they no longer have any real meaning.  JCE, e.g., was a
standlone technology which was folded into the JDK many releases ago and
hasn't really had its own version number since.  So to do this right
you'd need to figure out what's a "standard" and what's not, which could
take a fair bit of time, and it's not worth introducing new custom tags
if we aren't going to do it right.

I suggest you just retain the secondary version numbers and list them
after the primary, e.g.,

 * @since 1.6, SAX 2.0

I suggest you limit your patch only to change the @since tags.  That
will make it easier to review and easier to comprehend later on.  The
whitespace cleanup can be done separately.
