Now this is really frightening! How could anyone possibly outguess the
system to know what the result would be???
BTW, I tried the example on the W3C Schema Validator, and it reported that
it passed, but using lax validation because there was no declaration for
element "bar".

Changing the code to
var schemas = new ActiveXObject("MSXML2.XMLSchemaCache.4.0");
schemas.add("http://www.example.org";, "cyclic.xsd");
var x = new ActiveXObject("MSXML2.DOMDocument.4.0");
x.async = false;
x.schemas = schemas;
x.validateOnParse = false; /* don't validate on parse */
x.load("example.xml");
var vError = x.validate(); /* validate, grabbing error object (if any)
*/
/* print error message */
if(vError.reason != "")
WScript.Echo("invalid: " + vError.reason);
else
WScript.Echo("valid");
Leads to "invalid: Validate failed because the root element had no
associated DTD/schema" being displayed. Changing the instance to
<foo xmlns="http://www.example.com"/>
results in successful validation.
