[Error] :2:273: cvc-elt.1: Cannot find the declaration of element 'didl:DIDL'.

[Richard Moster <ri...@moster.net>]

I have an XML file, referencing a schema that in turn imports another
schema.  When I use the SAX2 parser to parse with validation, I'm getting
the following error:

[Error] :2:273: cvc-elt.1: Cannot find the declaration of element
'didl:DIDL'.

didl:DIDL is the root element of the XML file and is declared in the
imported schema (see below).  The whole thing works just fine in XMLSpy5.

Is there a problem with the validation if the root element has a namespace
qualifier defined in the same element?  The file parses fine, but I'm
getting that error message.

The XML file starts off:

<?xml version="1.0" encoding="UTF-8"?>
<didl:DIDL xmlns:didl="namespace1" xmlns="namespace2"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="namespace2 F:/MyProjects/SCRPG/SCR_02.xsd">

where namespace1 and namespace2 are placeholders are placeholders for the
purpose of this email--the files actually use valid namespaces.

The beginning of the schema F:/MyProjects/SCRPG/SCR_02.xsd is:

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema targetNamespace="namespace2" xmlns:didl="namespace1"
xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns="namespace2"
