RE: [xml-dev] Help Needed to create an XSD

["Cyril" <cyrilw@technicost.com>]

Thanks Michael and Anne T.

Just to consolidate my understanding about namespaces I think this is where
I was confused.

In my XML Data when there is no namespace prefix in the xml tag (for
<rptTransmit/>), doesn't it use the default namespace? I figured since my
default namespace has no definition of any element called rptTransmit, this
would be invalid. 

I saw from your example you use a reference eg ref="foo:rptTransmit" or
ref="i:rptTransmit" with the prefix , should this prefix appear in the XML
Data I am creating ie <foo:rptTransmit> instead of just <rptTransmit>? Or is
the latter valid? I'm having trouble understanding how the parser would know
that the <rptTransmit> is from the external XSD since it has no prefix for
the namespace.

Something like this:

<xs:schema>

<xs:import namespace="http://www.foo.ca/XMLSchemas";
        schemaLocation="http://www.foo.ca/XMLSchemas/UAT/Transmit.xsd"/>

<xs:element name="myrpt">
  <xs:sequence>
    <xs:element name="id"/>
    <xs:element name="status"/>
    <xs:element ref="i:rptTransmit" xmlns:i="http://www.foo.ca/XMLSchemas"/>
  </xs:sequence>
</xs:element>

</xs:schema>

That's just a sketch leaving out all the noise, but I hope you get the idea.
