\doxysubsection{Detailed Description}
Represents the canonical (X, Y, Z) composition of stellar material. 

This is a standard astrophysical representation where\+:
\begin{DoxyItemize}
\item X is the total mass fraction of all hydrogen isotopes.
\item Y is the total mass fraction of all helium isotopes.
\item Z is the total mass fraction of all other elements (metals). By definition, X + Y + Z should sum to 1.\+0. 
\end{DoxyItemize}
