Note

The arc element must be used if the arcs are labeled. Otherwise, arcs can be encoded using the @adj, @adjTo and @adjFrom attributes on the node tags in the graph. Both arc tags and adjacency attributes can be used, but the resulting encoding would be highly redundant.

Zero, one, or two children label elements may be present. The first occurrence of label provides a label for the arc; the second provides a second label for the arc, and should be used if a transducer is being encoded.

Example

<arc from="#T3" to="#T3">
  <label>OLD</label>
  <label>VIEUX</label>
</arc>
