How can I fix element so it can obtain default values if omitted

[john mattucci]

Im trying to create an element "refresh" which contains both a "time" & "timeType" element. If these elements are not included in .xml they will be replaced by the default values. However Im not sure what to place in ********* because I cant place <xs:sequence> because it will throw an error if I skip either of the "time" or "timeType" elements. Sorry i'm new to schemas how would I go about getting it to work?

Thank you all for your time

.........
<xs:element name="time" type="xs ositiveInteger" default="1"/>
<xs:element name="timeType" default="weeks">
<xs:simpleType>
<xs:restriction base="xs:string">
<xs:enumeration value="days"/>
<xs:enumeration value="weeks"/>
</xs:restriction>
</xs:simpleType>
</xs:element>
<xs:element name="refresh">
<xs:complexType>
************
<xs:element ref="time"/>
<xs:element ref="timeType"/>
*************
</xs:complexType>
</xs:element>

You can still use sequence if you make the elements in the sequence optional. Or you could use a sequence of choice. Depending on exactly what input variations you need to accept, this may be all you need.

I have tried both

<xs:complexType>
<xs:sequence>
<xs:element ref="time"/>
<xs:element ref="timeType"/>
</xs:sequence>
</xs:complexType>

which results in an error if I omit one or both of the elements from my .xml.

And

<xs:complexType>
<xs:choice>
<xs:element ref="time"/>
<xs:element ref="timeType"/>
</xs:choice>
</xs:complexType>

which throws no error if either the "time" or "timeType" is included but fails to add the default value if one is omitted.

You can get rid of this validation error by using the minOccurs and maxOccurs attributes like this:

<xs:complexType>
    <xs:sequence>
        <xs:element ref="time" minOccurs="0" maxOccurs="1" />
        <xs:element ref="timeType" minOccurs="0" maxOccurs="1" />
    </xs:sequence>
</xs:complexType>

This does not solve my issue. If I include minOccurs="0" maxOccurs="1" and the element is not included in the .xml the default value is never selected.
I have the following

<xs:element name="time" type="xs ositiveInteger" default="1"/>
<xs:element name="timeType" default="weeks">
<xs:simpleType>
<xs:restriction base="xs:string">
<xs:enumeration value="days"/>
<xs:enumeration value="weeks"/>
</xs:restriction>
</xs:simpleType>
</xs:element>

and if the elements are not included I wish to have the default inserted
