Although the article is bit light on specifics (or I missed them),
this does look very interesting:

looks like Linux + open source java combination can run circles around
equivalent Microsoft offering.
That is not altogether surprising, based on little I have heard from
.net stack (etc), and especially due to maturity of Java open source
packages used here. But it is good to get confirmation on suspicions.

Also: I am trying to finally tackle the only 2 major missing pieces
wrt Stax 1.0 compliancy that Aalto (blocking) has:

* Namespace-repairing mode for XMLStreamWriter
* Coleascing mode for XMLStreamReader.

I will probably start with the repairing mode, and then get coalescing
mode done. Getting these done might be enough to get us to 1.0
version.

Also: I would really appreciate feedback from anyone who has taken
Aalto to test ride -- while Google will eventually bring some results
to my attention, it would be sweet to hear things directly from users.
