Defining Elements to Contain Only Elements : complexType « XML Schema « XML Tutorial

An element with the most basic of complex types can contain other elements, and possibly attributes as well-but not text.
The elements contained within a complex type must be part of a sequence, choice, unordered group, or named group.
<?xml version="1.0"?>
<xsd:schema xmlns:xsd=""
  targetNamespace="" xmlns=""

  <xsd:complexType name="endspeciesType">
      <xsd:element name="animal" type="xsd:string" />
