To be more concrete, we have your original 2 types (using the new syntax
from [3]):

<xsd:simpleType name="Name1">
	<xsd:restriction base='xsd:string'>
		<xsd:enumeration value="RED"/>
		<xsd:enumeration value="BLUE"/>
	 	<xsd:enumeration value="GREEN"/>
	</xsd:restriction>
 </xsd:simpleType>

<xsd:simpleType name="Name2">
	<xsd:restriction base='xsd:string'>
		<xsd:enumeration value="BIG"/>
		<xsd:enumeration value="SMALL"/>
	</xsd:restriction>
</xsd:simpleType>

Then, we can create a list type whose "itemType" is given as an anonymous
simpleType that is the union of the 2 Name types, as in:

<xsd:simpleType name='NameList'>
	<xsd:list>
		<xsd:simpleType>
			<xsd:union memberTypes='Name1 Name2'/>
		</xsd:simpleType>
	</xsd:list>
</xsd:simpleType>

Hope this helps,

pvb
