Since it can hold elements, it must be an element of a complex type:

<xs:element name="text">
  <xs:complexType>
    ...
  </xs:complexType>
</xs:element>

Since it can also hold text, it must be a complex type with mixed
content:

<xs:element name="text">
  <xs:complexType mixed="true">
    ...
  </xs:complexType>
</xs:element>

Then the content model is just the same as it would be if <text>
*only* held the <bob> elements:

<xs:element name="text">
  <xs:complexType mixed="true">
    <xs:sequence>
      <xs:element ref="bob" minOccurs="0" maxOccurs="unbounded" />
    </xs:sequence>
  </xs:complexType>
</xs:element>

Cheers,

Jeni
