This example is a formal representation for the referencing scheme described informally in the following example.

Example
<refsDecl>
 <p>References are made up by concatenating the value for the
 <att>n</att> attribute on the highest level <gi>div</gi>
   element, followed by a space, followed by the sequential
   number of the next level <gi>div</gi> followed by a colon
   followed by the sequential number of the next (and lowest)
   level <gi>div</gi>.</p>
</refsDecl>
