XInclude usage and xsi:noNamespaceSchemaLocation limitation, workaround?

[aydns7]

First, thank you for being indulgent, I am an XML Schema beginner.I have build a XML file split up with several includes, using XInclude. I have chosen this method above others because each included XML files can be standalone validated.As I am working on local file, I didn't defined any namespace and then I use xsi:noNamespaceSchemaLocation attribute to reference my xsd file.parameters.xml\[code\]<?xml version="1.0" encoding="UTF-8"?><Root xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="parameters.xsd"> <xi:include href="http://stackoverflow.com/questions/13762041/Transducers/transducers.xml" parse="xml" xmlns:xi="http://www.w3.org/2001/XInclude"/></Root>\[/code\]parameters.xsd\[code\]<?xml version="1.0" encoding="UTF-8"?><xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" attributeFormDefault="unqualified"> <xs:include schemaLocation="./Transducers/transducers.xsd"/> <xs:element name="Root"> <xs:complexType> <xs:sequence> <xs:element ref="Transducers" minOccurs="1" maxOccurs="1"/> </xs:sequence> </xs:complexType></xs:element></xs:schema>\[/code\]Tranducers/transducer.xml\[code\]<?xml version="1.0" encoding="UTF-8"?><Transducers xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="./transducers.xsd">...</Transducers>\[/code\]I don't put the transducers.xsd file because it doesn't give anymore added value to the problem. Just take into account that the transducer.xml is valid against his schema.So, when I try to validate parameters.xml I got the following error :The 'noNamespaceSchemaLocation' attribute references a schema whose target namespace was already used for validation.Error that I can easily understand, but I can not get around in my situation.What would be the solution in that case. Thanks.
