DOCBOOK: DocBook XML and XMLspy

I am looking for a Win32 solution for structured/guided editing
of DocBook XML which is a bit closer to the standard Windows way 
of things than Emacs/PSGML. XMLspy seems to be a good choice 
(other suggestions?). 

If anybody has experience in using XMLspy to edit DocBook XML 
documents using either the DTD or the Schema, I'd appreciate 
comments. I found a few mentions of problems/bugs in mailing list
archives, but not many, which could either indicate it's a 
combination that works well, or indicate it is seldomly used.

Thanks,

                                             b.
