There are three different ways to declare your XSDs. It does not matter which way you choose, or how you combine them, as long as the XSD Adapter can find all needed schemas.
Within the Workflow:
org.eclipse.xtend.typesystem.xsd.XSDMetaModel can have any
amount of schemaFile elements.
<component class="org.eclipse.xtend.typesystem.xsd.XMLReader">
<modelSlot value="model" />
<uri value="${file}" />
<metaModel id="mm" class="org.eclipse.xtend.typesystem.xsd.XSDMetaModel">
<schemaFile value="model/loadcurve.xsd" />
<schemaFile value="model/device.xsd" />
</metaModel>
</component>
Within the XML file: XML files can contain
schemaLocation attributes which associate the
schema's namespace with the schema's filename. If the schema is
created using WTP like described in the section called “Step 3: Create a Model using XML” , the
schemaLocation attribute is created
automatically.
<?xml version="1.0" encoding="UTF-8"?> <device:Device xmlns:device="http://www.eclipse.org/modeling/xpand/example/model/device" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.eclipse.org/modeling/xpand/example/model/device device.xsd"> <device:Name>MyLaptop</device:Name> </device:Device>
Within an XSD: If one schema imports another, the
import element can have a
schemaLocation attribute, too.
<?xml version="1.0" encoding="UTF-8"?>
<schema
targetNamespace="http://www.eclipse.org/modeling/xpand/example/model/device"
elementFormDefault="qualified" xmlns="http://www.w3.org/2001/XMLSchema"
xmlns:tns="http://www.eclipse.org/modeling/xpand/example/model/device"
xmlns:lc="http://www.eclipse.org/modeling/xpand/example/model/loadcurve"
xmlns:ecore="http://www.eclipse.org/emf/2002/Ecore">
<import
namespace="http://www.eclipse.org/modeling/xpand/example/model/loadcurve"
schemaLocation="loadcurve.xsd">
</import>
<complexType name="Device">
<sequence>
<element name="Name" type="string" />
<element name="LoadCurve" type="lc:LoadCurve" />
</sequence>
</complexType>
<element name="Device" type="tns:Device"></element>
</schema>
