"Current" list of XML IDEs?

["Roger L. Costello" <costello@mitre.org>]

Hi Folks,

I need to do an evaluation of XML integrated development environments
(IDEs).  A cursory search yielded tools with announcements dated a year
or two ago.  I suspect that many of those tools are no longer being
used.  What are the hot tools "today"?

Specifically, I am looking for XML IDEs which supports **some or all**
of these capabilities:

 - XML editor
 - XML parser
 - XSL editor
 - XSL processor
 - XML Schema editor
 - XML Schema validator
 - DTD <--> Schema converter
 - HTML --> XHTML converter

/Roger
