The following XML file is generated for the preceding code example.

<?xml version="1.0" encoding="IBM437"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">

    <xs:simpleType name="NameType">
        <xs:restriction base="xs:string">
            <xs:whiteSpace value="collapse"/>
        </xs:restriction>
    </xs:simpleType>

    <xs:element name="LastName" type="NameType"/>
</xs:schema>

Remarks

The XmlSchemaWhiteSpaceFacet class defines how the simpleType value's white space will be treated. The whiteSpace facet value can be one of preserve, replace, or collapse.
