But as far as I know, the use of xs:all is quite restricted. One of the restrictions is that you can only have maxOccurs="0" or maxOccurs="1" within an xs:all, which eliminates the possibility to have an unrestricted number of occurences of the three types within the FormType. Look at the problem another way: The restriction in this case is a choice between three different types of elements, and the choice can be done an unrestricted number of times. Which gives us the schema below, which I think will do the trick:
<xs:complexType name="FormType">
<xs:choice minOccurs="0" maxOccurs="unbounded">
<xs:element name="TextBox" type="TextBoxType"/>
<xs:element name="TextArea" type="TextAreaType"/>
<xs:element name="Header" type="HeaderType"/>
</xs:choice>
</xs:complexType>
