Remarks

When the EnableUpaCheck property is set to false, validation will be performed based on the following rules.

1. If there is a choice between a strong type and a wildcard, the XmlSchemaSet will pick the strongly typed particle as illustrated in the following schema and Xml examples.

<xs:sequence>

<xs:any namespace="##any"/>

<xs:element name="A" type="xs:string" minOccurs="0"/>

</xs:sequence>

In the following Xml, the A element will be associated with <xs:element name="A" type="xs:string" minOccurs="0"/> in the schema.

<A>some text</A>

1. If there is a choice between two strongly typed elements, the XmlSchemaSet will pick the first one.

<xs:sequence>

<xs:element name="A" type="xs:string"/>

<xs:element name="B" type="xs:string" minOccurs="0"/>

<xs:element name="B" type="xs:string"/>

</xs:sequence>

In the following Xml, the B element will be associated with <xs:element name="B" type="xs:string" minOccurs="0"/> in the schema.

<A/>

<B/>
