Fabulous note this afternoon to the libxml mailing list:

The reason for this email is to really congratulate the people that wrote
this software. I am on AIX (IBM rs6000). I needed no help at all beyond
the supplied documentation and web site. Everything works as
documented. The interfaces are easy to understand and implement.

My background is 20+ years 'C' programming experience and almost no xml
experience. One of the easiest packages to integrate I have ever found --
even for the xml ignorant. The code is very readable and well structured
and written, making anything not completely documented in text easy to find
in the source.
