      ( element * - rng:* { ... }* )
    & (

Description:

The mixed pattern is a shortcut for interleave with an embedded text pattern. It describes unordered content models where a text node may be included before and after each element. Note that RELAX NG does not allow the addition of constraints on these text nodes.

Restrictions:

The limitations of interleave apply here:

The mixed pattern cannot be used within a list.
Elements within a mixed pattern cannot have overlapping name classes.
There must no other text pattern in each set of patterns combined by mixed.

Example:

    <element name="title">
     <mixed>
      <attribute name="xml:lang"/>
      <zeroOrMore>
       <element name="a">
        <attribute name="href"/>
        <text/>
       </element>
      </zeroOrMore>
     </mixed>
    </element>
 
is equivalent to:
 
    <element name="title">
     <interleave>
      <text/>
      <group>
        <attribute name="xml:lang"/>
        <zeroOrMore>
         <element name="a">
          <attribute name="href"/>
          <text/>
        </element>
        </zeroOrMore>
      </group>
     </interleave>
    </element>
 
which itself is equivalent to:

    <element name="title">
     <interleave>
      <text/>
      <attribute name="xml:lang"/>
      <zeroOrMore>
       <element name="a">
        <attribute name="href"/>
        <text/>
      </element>
      </zeroOrMore>
     </interleave>
    </element>

Attributes:

datatypeLibrary: The datatypeLibrary attribute defines the default datatype library. The value of datatypeLibrary is inherited.
ns: The ns attribute defines the default namespace for the elements defined in a portion of a schema. The value of ns is inherited.
