RelaxNG, because it

- is quite powerful and flexible
- is very easy and intuitive to read and write
- is straightfoward to customize
- works with James Clark's nxml-mode for Emacs

Emacs, because I use Emacs for almost everything.

nxml-mode, because it does many things for me, most importantly

- on-the-fly validation
- tag autocompletion
- all the basic stuff (syntax highlighting, auto-indentation, ...)

For me, its most serious shortcoming is the absence of built-in
support for XIncludes (together with a choice of "shallow" and "deep"
validation).  I help myself with customized RelaxNG schemas where I
allow xi:includes wherever I need them in practice.

> 3.  What validation tools you are using, and why.

- nxml-mode for on-the-fly, "shallow" validation (using schemas that
  allow xi:includes)

- xmllint --xinclude followed by jing for "deep" validation (within an
  Emacs compilation buffer, of course)

  Why? The main reason is that I heavily use the xpointer() scheme
  (http://www.w3.org/TR/xptr-xpointer/) in my xi:includes, which is
  not widely implemented. This essentially limits me to libxml.

  Jing can use the same compact-syntax RelaxNG schema as uses
  nxml-mode.
