例

The following example is discussed in section 16.7 Aggregation:

<sp>
 <speaker>Hughie</speaker>
 <p>How does it go?
 <q>
   <l xml:id="frog_x1">da-da-da</l>
   <l xml:id="frog_l2">gets a new frog</l>
   <l>...</l>
  </q>
 </p>
</sp>
<sp>
 <speaker>Louie</speaker>
 <p>
  <q>
   <l xml:id="frog_l1">When the old pond</l>
   <l>...</l>
  </q>
 </p>
</sp>
<sp>
 <speaker>Dewey</speaker>
 <p>
  <q>...
  <l xml:id="frog_l3">It's a new pond.</l>
  </q>
 </p>
 <join targets="#frog_l1 #frog_l2 #frog_l3" result="lg" scope="root"/>
</sp>

The join element here identifies a linegroup (lg) comprising the three lines indicated by the targets attribute. The value root for the scope attribute indicates that the resulting virtual element contains the three l elements linked to at #frog_l1 #frog_l2 #frog_l3, rather than their character data content.

例

In this example, the attribute scope is specified with the value of branches to indicate that the virtual list being constructed is to be made by taking the lists indicated by the targets attribute of the join element, discarding the list tags which enclose them, and combining the items contained within the lists into a single virtual list:

<p>Southern dialect (my own variety, at least) has only
<list xml:id="LP1">
  <item>
   <s>I done gone</s>
  </item>
  <item>
   <s>I done went</s>
  </item>
 </list> whereas Negro Non-Standard basilect has both these and
<list xml:id="LP2">
  <item>
   <s>I done go</s>
  </item>
 </list>.</p>
<p>White Southern dialect also has
<list xml:id="LP3">
  <item>
   <s>I've done gone</s>
  </item>
  <item>
   <s>I've done went</s>
  </item>
 </list> which, when they occur in Negro dialect, should probably
be considered as borrowings from other varieties of
English.</p>
