Question

I would like to ask about .XSD document. I cannot find anything about creating my own type, for example:

<?xml version="1.0"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">

    <xs:complexType name="Client">
        <xs:sequence>
            <xs:element name="FirstName" type="string"/>
            <xs:element name="SecondName" type="string"/>
    </xs:sequence>
    </xs:complexType>

    <xs:complexType name="Contact">
        <xs:sequence>
            <xs:element name="contacts" type="Client"  minOccurs="1"/>
        </xs:sequence>
    </xs:complexType>   
</xsd:schema>

And I would like to know is that right way to define my own type contact?

Answer 1

A few points that were not quite right.

• The xsd: namespace alias on the closing schema tag should be just xs:

• The primitive string types need there types qualifying, ie xs:string.

• From a style point of view ComplexTypes should end Type.

• If you want to use the schema (presumably via the Contact) then you need to declare a root element.

<?xml version="1.0" encoding="utf-8" ?>

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
    <xs:complexType name="ClientType">
        <xs:sequence>
            <xs:element name="FirstName" type="xs:string" />
            <xs:element name="SecondName" type="xs:string" />
        </xs:sequence>
    </xs:complexType>
    <xs:complexType name="ContactType">
        <xs:sequence>
            <xs:element name="contacts" type="ClientType" minOccurs="1" />
        </xs:sequence>
    </xs:complexType>
    <xs:element name="Client" type="ClientType" />
</xs:schema>

Basically XML Schemas are complex things to write without a tool. I’d seriously look into getting a good schema designer, I’d recommend Liquid XML Studio.
