[XeTeX] xunicode and TIPA

[Alan Munn]

Hi

The xunicode package provides a textipa command which recognizes (most  
of?) the commands from the tipa package.  This is very useful, since  
it allows one to convert legacy documents containing IPA to xelatex  
with minimal trouble.  However, the tipa package also provided an IPA  
environment.  This is not supplied by xunicode.  Is there a way to  
emulate that too?  Here's a minimal document:

I know the definition for the IPA environment isn't correct; what I  
want is characters inside that environment to be interpreted in the  
same way that they are within the \textipa command provided by xunicode.

% !TEX TS-program = XeLaTeX
\documentclass{article}
\usepackage{xltxtra}
\newfontfamily{\ipafont}{Doulos SIL}
\def\useTIPAfont{\ipafont}
\newenvironment{IPA}{\ipafont}{} % I know this isn't sufficient
\begin{document}
\textipa{RPAQIOE} % This will give you correct phonetic characters
\begin{IPA}RPAQIOE % This obviously doesn't
\end{IPA}

\end{document}
