Re: any JSR that describe on presence's PIDF ?

Man-Chi,

I don't know about a JSR, but for SipUnit I used JAXB which was probably 
overkill and isn't completely perfect, yet anyway. But simple - given an 
XMLSchema definition and a jaxb compiler, Java classes are autogenerated 
that you can then use to parse and validate a received XML doc. You can 
look at the SipUnit project source dir (download from cafesip.org), the 
parts of interest are the build.xml (for jaxb compiling), 
conf/presence-pidf.xsd, and the app code that uses it 
(org.cafesip.sipunit.Subscription) - method below, called after 
validating the NOTIFY headers. The classes you see like 'Tuple' are the 
autogenerated ones.
