I have an XSD file in which I would like to place several diagrams, with a description of the services. When adding

<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
            elementFormDefault="qualified"
            attributeFormDefault="qualified"
            targetNamespace="[target1]"
            xmlns:tns="[target1]">

</xsd:schema>

<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
            elementFormDefault="qualified"
            attributeFormDefault="qualified"
            targetNamespace="[target2]"
            xmlns:tns="[target2]">
</xsd:schema>

I get error: "Multiple root tags"

If I write like this:

<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
            elementFormDefault="qualified"
            attributeFormDefault="qualified"
            targetNamespace="[target1]"
            xmlns:tns="[target1]">
    <xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
            elementFormDefault="qualified"
            attributeFormDefault="qualified"
            targetNamespace="[target2]"
            xmlns:tns="[target2]">
    </xsd:schema>
</xsd:schema>

I get error:

Invalid content was found starting with element '{"http://www.w3.org/2001/XMLSchema":schema}'. One of '{"http://www.w3.org/2001/XMLSchema":simpleType, "http://www.w3.org/2001/XMLSchema":complexType, "http://www.w3.org/2001/XMLSchema":group, "http://www.w3.org/2001/XMLSchema":attributeGroup, "http://www.w3.org/2001/XMLSchema":element, "http://www.w3.org/2001/XMLSchema":attribute, "http://www.w3.org/2001/XMLSchema":notation, "http://www.w3.org/2001/XMLSchema":annotation}' is expected.

Is it possible to configure an XSD file to consist of multiple schemas xsd:schema?

CodePudding user response：

XSDs cannot be composed by embedding xsd:schema elements like that.

To incorporate multiple XSDs with distinct targetNamespaces, use xsd:import.

CodePudding user response：

You are only allowed to have one schema, but this schema can declare several elements suitable as root, and underneath those you could have completely disjunct tree structures.
