Xsd, Validate empty or minimum length string

Question

Currently I have an Xsd validating with this rule

<xs:simpleType name='shipTo'>
    <xs:restriction base='xs:string'>
        <xs:minLength value='6'/>
    </xs:restriction>
</xs:simpleType>

I need to allow blanks as well, but if a value is entered, it's minimum length should still be 6.

Can I do this without resorting to this xs:pattern and regex?

<xs:simpleType name='shipTo'>
    <xs:restriction base='xs:string'>
        <xs:pattern value='^(?:|[\w]{6,})$'/>
    </xs:restriction>
</xs:simpleType>

The regex will work, but you should really make the element that you will be assigning shipTo to optional, and not include it in the XML file if it has no value.

Yeah, that would make more sense. Unfortunately, I don't control the consumer of said xml...which is not written well.
