Schema issue with enumerated element content

Hi,

I am trying to define an element that does two things:

1 - Provides an enumerated list of valid text content items, allowing multiple items

2 - Provides an attribute.

So far, I have the following, which satisfies #1, but I can't figure out how to add an attribute. Any ideas?

Thanks in advance,

Russ

<xs:element name="ElemName">

<xs:complexType>

<xs:simpleContent>

<xs:restriction base="xs:anyType">

<xs:simpleType>

<xs:list>

<xs:simpleType>

<xs:restriction base="xs:string">

<xs:enumeration value="Value1"></xs:enumeration>

<xs:enumeration value="Value2"></xs:enumeration>

<xs:enumeration value="Value3"></xs:enumeration>

<xs:enumeration value="Value4"></xs:enumeration>

</xs:restriction>

</xs:simpleType>

</xs:list>

</xs:simpleType>

</xs:restriction>

</xs:simpleContent>

</xs:complexType>

</xs:element>

I'd like to create a valid element in the XML such as:

<ElemName attr="value">Value1 Value2</ElemName>
