numbering some equations in <align>...</align> doesn't work

[GoogleCodeExporter]

This:

            You can also number some of them, e.g. <a ref="eq5"/>:
            <align>
                <e>x^3 + y^n = z^n</e>
                <e id="eq5">x^4 + y^n + w^3 = z^n</e>
            </align>

produces:

 You can also number some of them, e.g. (\ref{eq5}):
\begin{eqnarray*}
x^3 + y^n &=& z^n \\
x^4 + y^n + w^3 &=& z^n \\
\end{eqnarray*}

It should be more clever and assign \label{} and \nolabel where appropriate.
