RE: [xml-dev] Duplicate element decl in the same scope

[Bryan Rasmussen <bry@itnisk.com>]

I forgot to cc xml-dev, to make sure it gets to you (since I've been having some
problems with my web-based mail i will send this there now)

the following fragment 
<xs:element name="root" type="one:blah">
	<xs:unique name="element1">
		<xs:selector xpath="one:element"></xs:selector>
		<xs:field xpath="@name"></xs:field>
	</xs:unique>
	</xs:element>
	<xs:complexType name="blah">
		<xs:sequence>
			<xs:element name="element" minOccurs="0" maxOccurs="unbounded">
				<xs:complexType>
					<xs:attribute name="name" type="xs:string"/>
				</xs:complexType>
			</xs:element>
					</xs:sequence>
	</xs:complexType>

without a specific type for the name attribute does the uniqueness constraint.
