I tried it now with these 2 files:

,----[ This is uwe-xr.tex ]
| \documentclass[12pt]{article}
| \usepackage{xr-hyper}
| \externaldocument{uwe-master}
| \usepackage[colorlinks]{hyperref}
| 
| \begin{document}
| 
| This is true \ref{eq:master1}
| 
| (symbol-value reftex-docstruct-symbol)
| 
| \end{document}
| 
| %%% Local Variables:
| %%% mode: latex
| %%% TeX-master: t
| %%% End:
`----

,----[ This is uwe-master.tex ]
| \documentclass[12pt]{article}
| \usepackage{amsmath,amsthm}
| \usepackage[colorlinks]{hyperref}
| 
| \begin{document}
| this is an equation 
| \begin{equation}
|   \label{eq:master1}
|   \int f dx
| \end{equation}
| \end{document}
| 
| %%% Local Variables:
| %%% mode: latex
| %%% TeX-master: t
| %%% End:
`----

And it works.  In uwe-xr.tex, I hit `C-c ) RET SPACE x' and I get this
in *RefTeX Select*:

>               eq:master1
.                 \int f dx 

Eval'ing the symbol-value form contains an entry for `xr-doc'.

Are the files in the same directory?

Good question, I have to check.
