JAXP 1.4 is now final. This is a "maintenance release" (JSR 206) but a substantial one. The main new addition is support for StAX (JCP, wikipedia) but there are other changes too (Change Log). This is the same version that goes into Java SE 6; you can also use it with JRE 1.4 and JRE 5.0 using the Endorsed Standard Override mechanism.
The implementation is delivered as two JARS (API + Impl) for simplicity and uses the StAX and JAXP implementations from GlassFish which build on Xerces 2 Java. Check the blogs from Santiago and Norm for some more details.
All this code is Open Source, and so will be the implementation of the next version of the spec.
