"Methods"?  Did you "Master"?

Anyway, a few hours ago was installed in AUCTeX a new patch that
should improve your workflow with this package.  For example, this is
my master file:

--8<---------------cut here---------------start------------->8---
\documentclass{article}
\usepackage{subfiles,amsmath}
\begin{document}
hello world!
\begin{equation}
  \label{eq:1}
  a + b = c
\end{equation}
\subfile{file1.tex}
\end{document}

%%% Local Variables:
%%% mode: latex
%%% TeX-master: t
%%% End:
--8<---------------cut here---------------end--------------->8---

and this is my file1.tex file:

--8<---------------cut here---------------start------------->8---
\documentclass[master.tex]{subfiles}

\begin{document}
Equation~\eqref{eq:1}
\end{document}

%%% Local Variables:
%%% mode: latex
%%% TeX-master: t
%%% End:
--8<---------------cut here---------------end--------------->8---

Inside file1.tex, now I can insert with RefTeX a reference defined in
another file (like what I did to insert the reference to "eq:1"
label).  Is this what you would like?

Bye,
