Schemas validity error : Element No matching global declaration available for the validation root

Question

I'm creating an XSD for validating a XML, but it gives me the following validation error:

$ xmllint --noout --schema imoveis.xsd imoveis.xml 
imoveis.xml:2: element alugueis: Schemas validity error : Element '{http://www.w3.org/2001/XMLSchema-instance}alugueis': No matching global declaration available for the validation root.
imoveis.xml fails to validate

Not sure what I'm forgetting.

Here is my XML:

<alugueis xmlns="http://www.w3.org/2001/XMLSchema-instance"
          noNamespaceSchemaLocation="imoveis.xsd"
          mes="outubro" ano="2012">

And here my validating XSD:

<schema xmlns="http://www.w3.org/2001/XMLSchema"
        targetNamespace="simulado"
        xmlns:doc="simulado"
        elementFormDefault="qualified">

Answer 1

Fix your XML in this way:

<alugueis xmlns="simulado"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="simulado imoveis.xsd"
          mes="outubro" ano="2012">

And your XSD should then be able to be found. You will have further fixes to make (eg condominio), but those should be self-explanatory. If not, feel free to post again.
