XML Editors

I'm looking for an XML editor with the following features to replace XMLSpy 2005:
- code-assist (xml from DTD, schema, xsl)
- a nice grid view (or good xPath support)
- easy auto-format
- XSLT preview/debugger
- Eclipse integration (optional but prefered)
- XPath 2.0 support (optional)
- Configurable parser (optional)

Here's what I've got so far:
XMLPad: Great auto-format, good code assist (doesn't know about xsl: namespace attrs), xslt preview, nice highlighting (large file support?)
Eclipse WTP & EE tools: Good highlighting, extensive auto complete
eclipseXSLT: (untested) good XPath/xslt support

What do you use for editing XML? Do you like it?

Anything you can contribute will be greatly appreciated!
