Thanks for posting this! As a Tamino user (we also use 3.x, and while I've played with 4.1 we haven't had time to upgrade yet), I'd just add a couple of notes:
One major enhancement of 4.1 you don't mention is support for XQuery. I mean the real W3C XQuery as opposed to the "X-Query" which, as you point out, is equivalent to XPath 1.0 plus some extensions and minus some features. I can't speak to how complete or compliant their XQuery functionality is. Also, their implementation of XML:DB is just a thin layer on top of their proprietary client API for Java (a DOM-based instantiation of it), and can be used with 3.x. I think they don't actually package it with the product until 4.1, but is available as a download from their developer community site. I'd really like to see some performance comparisons! I suspect where Tamino shines vs Xindice and eXist is performance and scalability. Also the devil with these things, beyond the big picture features, is in the details. For example, one reason we haven't upgraded to Tamino 4.1 is it would not support xsi:type. In 3.1 I can hack the schema to ignore it. In 4.1 it completely rejects it. There is supposed to be a patch for this now, but I have not yet tried it. These are the sort of little support details that can make or break whether a given XML database works for you--and especially details of what kinds of indexes the database supports well, and (partly due to this) what kind of queries does it perform well.
