Future Compatible Attributes
Attributes, or Meta Info, has been around in various libraries for a
while. The first foray into it that I can recall was with none other
than the Phoenix code at Avalon. That said, Java 1.5 has a version of
keeping meta info that has a slightly different syntax than any of the
dedicated libraries support. If there is any way to use a library that
supports Java 1.5 meta info as it is declared and used, then our users
won't have to change when they use these attributes in their own code.
This is a very important point as changes to user code is far more
reaching than changes to our code.
I am only vaguely familiar with the offerings, but we now have a spec
for the Java 1.5 attributes. Perhaps, if we have any control or
influence with a library, we can get them to support syntax that is
similar.

Theres no stable released project that uses a jdk1.5-like
model for attributes (and only one semi-developed one). And
there is no direct compatibility that I am aware of (though
this may have changed in the last few months).
It would be a lot of work to adapt a toolkit that reads and
writes jdk1.5 attributes but I am not sure it will happen.
jdk1.5 is just too close.

Actually, in Fortress there is no XML. It is all properties files.
Berin, another XML Critic by experience

MetaClass is written by PeterD and Mauro I think, and looking at the
docs has a syntax that's rather similar to jdk 1.5. There's also
commons-sandbox-attributes by Leo Sutic which I believe actually
supports or will suport JDK 1.5 but it doesn't seem as mature nor do I
think it offers all the things we need. We have meta stuff in xml; lets
keep it there for now...
