Article on GXA (Global XML Web Services Architecture)

This is not registry-related, but it is Web services-related:

For those who have been tracking GXA (of which WS-Security is a part),
or would simply like to learn more about it: I have written an article
on GXA for Developer.com [1]. I cover 10 of the (now 17) specifications,
including WS-Security, WS-Transaction, and WS-Policy.

Thanks,
Joe
