Looks like something is wrong with the manual.

[qiukun]

The xmllint and xsltproc programs to build this manual and the man-pages. These are part of the libxml2 and libxslt packages, respectively. You also need the DocBook XSL stylesheets and optionally the DocBook 5.0 RELAX NG schemas. Note that these are only required if you modify the manual sources or when you are building from the Git repository.

What does it mean? Is it means that i can install nix without xmllint and xsltproc?
Here the new msg:

sorry for not carefully reading the doc.

Could you list the required cygwin packages names, in order to build the doc?
