Description

The group pattern defines an ordered group of subpatterns. Note that when attribute patterns are included in such a group, their order isn't enforced. group patterns are implicit with element and define patterns.

Example

<element name="name">
  <choice>
   <text/>
   <group>
    <element name="first"><text/></element>
     <optional>
       <element name="middle"><text/></element>
     </optional>
     <element name="last"><text/></element>
    </group>
  </choice>
 </element>
<element name="foo">
  <interleave>
   <element name="out"><empty/></element>
   <group>
    <element name="in1"><empty/></element>
    <element name="in2"><empty/></element>
  </group>
 </interleave>
</element>
