Hello guys, I'm new to XML so sorry for probably 'obvious' question

I have the following xml schema

<!-- dynamicMeasurement.xsd -->

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

<xs:complexType name="dynamicObjectsContainer">
...
</xs:complexType>
...
</xs:schema>

<!-- dynamicObject.xml -->

<?xml version="1.0" encoding="UTF-8"?>
<measure:dynamicObjectsContainer
xmlns:measure="http://www.example.org"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.example.org dynamicMeasurement.xsd">

...
</measure:dynamicObjectsContainer>

But whenever I try to validate the xml file (I'm using oxygen plugin
for eclipse 3.1) I got

cvs-elt.1: Cannot find the declaration of element
'measure:dynamicObjectContainer'
@see: http://www.w3.org/TR/xmlschema-1/#cvs-elt

So the problem is: do I miss some kind of declaration, or namespace?
incredibly I believe I copied another xml, xsd definitions (stored in
another directory) which works without any problem.

Thanks in advance,
cheers

Hi,

You defined in the schema file a complex type with the name
dynamicObjectsContainer. The error says that there is no declaration
for the element with the local name dynamicObjectsContainer that you
use in your instance document. XML Schema does not automatically map an
element name to a type with the same name as the element. You need to
add to your schema an element declaration like below:

<xs:element name="dynamicObjectsContainer"
type="measure:dynamicObjectsContainer"/>

Best Regards,
George

Thank you very much for reply,

Indeed, looking with little bit more attention on some other xml
examples I can see how the elements declared in the schema and
referenced externally by xml files are usually constructed by

<xs:element name="A">
<xs:complexType>
</xs:complexType>
</xs:element>

but then another question arises naturally - the construction of type:

<xs:element name="dynamicObjectsContainer"
type="measure:dynamicObjectsContainer"/>

shouldn't get inside a infinite recursive loop, since it is declared of
the same type as it is itself?

but then another question arises naturally - the construction of type:

No, you have an element with the same name as a type, but they are
different components.
