Hi,

I am trying to use the XML schema shown below to validate an XML document
using the data type timeInstance.

<?xml version='1.0'?>

<xsd:schema xmlns:xsd="http://www.w3.org/1999/XMLSchema"
            xmlns:xdt="http://www.w3.org/1999/XMLSchema-datatypes">

	<xsd:element name="service" type="Service"/>

	<xsd:complexType name="Service">
		<xsd:element 	name="details" 	type="Details"
minOccurs="1"/>
	</xsd:complexType>

	<xsd:complexType name="Details">
		<xsd:element	name="type"		type="xsd:string"/>
		<xsd:element	name="start"	type="xdt:timeInstance"/>
		<xsd:element	name="stop"
type="xdt:timeInstance"/>
	</xsd:complexType>
	
</xsd:schema>

but when the validator I am using (Xerces 1.1.3) tries to validate the
document it states that it cannot resolve URI : http:
//www.w3.org/1999/XMLSchema-datatypes to a SchemaGrammar in
getTypeInfoFromNS.

As I am new to XML I may well be missing something really obvious but I was
under the impression that I had used the correct format to use the schema
datatype timeInstance after giving it the alias of xdt.

If anyone can point out where I am going wrong it will be most appreciated.

Cheers,
Neil
