%% Here we need how this meta model translates into the FMMD Hierarchy
\subsection{How the UML Meta Model maps to an FMMD Hierarchy}
The UML meta model above (see figure~\ref{fig:cfg}) describes a hierarchical structure. %% Might be a UML pattern that is well known ..... 05MAY2012
This is because, as {\dcs} inherit the properties of
components, {\dcs} may be used to form {\fgs}.
%
Consider the hierarchy from the example in figure~\ref{fig:dc2}.
The lowest level in this hierarchy are the {\bcs}, the resistors and the op-amp.
%
The resistors are collected into a {\fg}, and the ${PD}$ derived component is created above them.
%
As this derived component inherits the properties of a component we may use
it in {\fg} higher in the hierarchy.
%
The $PD$ derived component is now placed into a functional group
with the op-amp.
%
This {\fg} is now analysed and the a {\dc} created to
represent the failure mode behaviour of the $INVAMP$.
%
We may now use the $INVAMP$ {\dc} in even higher level {\fgs}.
\subsection{Keeping track of the derived components position in the hierarchy}
\label{sec:alpha}
The UML meta model in figure \ref{fig:cfg}, shows the relationships
