XML Schema newbie question

Posts: n/a
I have the following xml document that I want to create a schema for:

<?xml version="1.0" encoding="utf-8" ?>
<CheckPoints xmlns="">
<CheckPoint id="uniqueID">
<case value="value1" actiontype="HOLD" action="action1" />
<case value="value1" actiontype="STATUS" action="action2" />
<case value="value1" actiontype="CLASS" action="action3" />
<case value="value1" actiontype="URL" action="action4" />

I want to develop a schema document that will limit the values for
"actiontype" to HOLD, STATUS, CLASS, or URL. Because I'm a newbie to
schema document creation, I used the schema generator within Visual
Studio. It generated the following schema:

<?xml version="1.0"?>
<xs:schema id="CheckPoints"
attributeFormDefault="qualified" elementFormDefault="qualified">
<xs:element name="CheckPoints" msdata:IsDataSet="true"
<xs:choice maxOccurs="unbounded">
<xs:element name="CheckPoint">
<xs:element name="case" minOccurs="0"
<xs:attribute name="value" form="unqualified"
type="xs:string" />
<xs:attribute name="actiontype" form="unqualified"
type="xs:string" />
<xs:attribute name="action" form="unqualified"
type="xs:string" />
<xs:attribute name="id" form="unqualified"
type="xs:string" />

Thanks for the help in advance.

You can use a restriction as below:

<xs:attribute name="actiontype" form="unqualified">
<xs:restriction base="xs:string">
<xs:enumeration value="HOLD"/>
<xs:enumeration value="STATUS"/>
<xs:enumeration value="CLASS"/>
<xs:enumeration value="URL"/>
