The only documentation is in xref.el itself.  In a nutshell, you need
to implement a couple of methods in a way that is specific to LaTeX.

(Btw, doesn't it already work?  Etags is an existing back-end for
Xref, and 'etags' the program already supports TeX and its
derivatives, so it is able to create TAGS tables for LaTeX files.)
