Interleave

["Kevin B. Doney" <kdoney@weststlouis.com>]

This is a basic question but I am trying to catch up. 

Within a choice, would interleave specify a group or would you still
have to explicitly specify the group

<element name="addressBook">
  <zeroOrMore>
    <element name="card">
     <choice>
      <anyString/>
      <interleave>
	<element name="name">
	  <anyString/>
	</element>
	<element name="email">
	  <anyString/>
	</element>
      </interleave>
     <choice/>
    </element>
  </zeroOrMore>
</element>

OR

<element name="addressBook">
  <zeroOrMore>
    <element name="card">
     <choice>
      <anyString/>
      <group>
       <interleave>
	<element name="name">
	 <anyString/>
        </element>
	<element name="email">
         <anyString/>
	</element>
       </interleave>
      <group/>
     <choice/>
    </element>
  </zeroOrMore>
</element>
