[sunxacml-announce] code update

[Seth P. <set...@su...>]

The latest CVS tree has two notable updates that I thought people might find
interesting:

 1. a small bug fix for AttributeValue encoding (thought this went in a while
    ago, but apparently I was wrong as someone hit up against this bug).

 2. a change in the constructors for RequestCtx so they now use a Subject
    class rather than a Set of Lists.

The second item in particular has been a common request, so I suspect that if
you're writing code that generates Requests you'll want to grab the latest
bits. I think it's pretty self-evident how the new interface works, but let
me know if you have any problems.
