  <p>This produces a many-to-one linkage in the HTML matcher graph.
  
  <p>Note that a {@link HtmlMatcherGraphNode} may occur in the list more than once, each time
  with a different active edge. For example, this Soy template body:
  
  <pre>
  &lt;span&gt;
  {if $cond1}Content1{/if}  // No HTML tags in the If-block.
  &lt;/span&gt;
  </pre>
  
  will add two occurences of an {@link HtmlMatcherConditionNode} to the {@code activeEdges} list,
  one with a {@code TRUE} active edge, and one with a {@code FALSE} active edge.
  
  @param activeEdges the list of all active edges that will point to this {@link
  HtmlMatcherAccumulatorNode}. Note that a {@link HtmlMatcherGraphNode} may occur in the list
  more than once.
