XML Schema -elements with restrictions(maxLenght) and Mandatory values

Question

I'm supposed to create a XML Schema for this.

Where column A is Tag Name column B is Data Type column C is Max length and column D is Mandatory

<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
    elementFormDefault="qualified">
    <xsd:complexType name="Applicant">
        <xsd:sequence>
            <xsd:element name="Surname" >
                <xsd:simpleType>
                    <xsd:restriction base="xsd:string">
                        <xsd:maxLength value="26" />
                    </xsd:restriction>
                </xsd:simpleType>
            </xsd:element>
            <xsd:element name="FirstName">
                <xsd:simpleType>
                    <xsd:restriction base="xsd:string">
                        <xsd:maxLength value="26" />
                    </xsd:restriction>
                </xsd:simpleType>
            </xsd:element>

        </xsd:sequence>
    </xsd:complexType>


//etc..
</xsd:schema>

And this is what I've tried yet.

But my problem is I'm not able to give Mandatory for complex type Applicant and element names (Surname,First name) because required is not available for elements. But it is available for attributes.

Plz Feel free to edit and comment for any clarifications

Thank You.

Answer 1

The default value of minOccurs and maxOccurs of a element is 1 .

So, by default, each element has to appear, if you don't define those parameters.

I'm not shure, but i have tested with success this xsd
