Cross Model Document

A cross model document must contain at least a default pattern-action. Here you have an example:

<?xml version="1.0" encoding="UTF-8"?>
<cross-model>
  <cross-action id="default" a="ebenimeli">
    <description>Default pattern</description>
    <pattern>
      <e>
        <p>
          <l>$lemmaA<v n="cat"/><t n="tailA"/></l>
          <r>$lemmaB<v n="cat"/><t/></r>

      </e>
      <e>
        <p>
          <l>$lemmaB<v n="cat"/><t/></l>
          <r>$lemmaC<v n="cat"/><t n="tailC"/></r>

      </e>
    </pattern>
    <action-set>
      <action>
        <e>
          <p>
            <l>$lemmaA<v n="cat"/><t n="tailA"/></l>
            <r>$lemmaC<v n="cat"/><t n="tailC"/></r>

        </e>
      </action>
    </action-set>
  </cross-action>
</cross-model>
