Re: [xml-dev] xml schema trouble

[Francis Norton <francis@redrice.com>]

Ian,

XML Schema is not as mature as XSLT, so even though there is a syntax
for what you propose to do it won't have any effect for now. You need to
install an XML Schema processing tool such as MSXML4, XSV or an eval
copy of XML Spy, and initiate validation explicitly. 

The syntax for suggesting (but only suggesting - the reader chooses what
to validate a message against, not the writer) is to add an XSI
schemalocation attribute (see
http://www.w3.org/TR/2001/REC-xmlschema-0-20010502/#schemaLocation) to
your root node, eg

	<myRoot xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
		xsi:noNamespaceSchemaLocation="AccountClosureDetails.xsd">

or

	<purchaseReport
               xmlns="http://www.example.com/Report"
               xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
               xsi:schemaLocation="http://www.example.com/Report
               http://www.example.com/Report.xsd">

You will find the primer (http://www.w3.org/TR/xmlschema-0/) very
helpful, also the tutorial by Roger Costello at
http://www.xfront.com/xml-schema.html
