RE: [xml-dev] [ANN] Ipedo XML Database 3.1 Now Available

Thanks for your response.

So now I have more questions: 

1.) So what happens if the XQuery WG decides to add update syntax & semantics which differ significantly from Jonathan Robie's draft as happened with Microsoft with both XSL/XSLT and XDR/XSD? 

2.) So since you have schema importation abilities and schema aware processing can you tell me the results of this query according to your product 

Given the following schema

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema";
  elementFormDefault="qualified"
  targetNamespace="http://www.example.com";
  xmlns:myns="http://www.example.com";>

 <xs:element name="foo" type="myns:fooType" />

  <xs:complexType name="fooType" >  
   <xs:element name="bar" minOccurs="3" maxOccurs="6" />
  </xs:complexType>

</xs:schema>

and the query

	schema namespace myns="http://www.example.com"; at "http:/www.example.com/foo.xsd"
	$foo = <myns:foo>{ document("http://www.example.org/bar.xml";)//myns:bar }</myns:foo>
	$foo instance of element of type myns:fooType

what is the result according to your product or do the above 3 lines utilize an unsupported feature? 

Thanks again for your answers.
