That would be because the asserted type should be validly derived from
the original type which, in this case, is not true.

Subject: xsi:type and xsd:string confusion


If I define a simple type thus (a string constrained only in that it
must 
have at least 1 character) :-

	<s:element name="CRN">
		<s:simpleType>
			<s:restriction base="s:string">
				<s:minLength value="1"/>
			</s:restriction>
		</s:simpleType>
	</s:element>

why is it that my validating parser reports that the following fragment 
which asserts the string type is invalid :-

<CRN xsi:type='xsd:string'>10165451</CRN>

the message output is :-

Use of type '{http://www.w3.org/2001/XMLSchema}string' is blocked on
element 
'{http://www.xxx}CRN'

Is there a way of maintaining the minLength facet and allowing run-time
type 
assertion like this ?

Fraser.
