xml and xsd not validating error

Question

I am a newbie in xml and all and i have been assigned a task to make an xml file to load configuration in a c++ program. Since i have never done this before i used xml copy editor to create the following xml and then selected the create schema option to create a xsd for the xml however when i am trying to validate it is giving error. can someone tell me what i am doing wrong.

I have not written the c++ code as my first priority is to create a valid xml and xsd.

xml :

<?xml version="1.0" encoding="UTF-8"?>
<part_id>
   <class_id>
      <head>

for validation I went to :https://www.freeformatter.com/xml-validator-xsd.html

Error: S4s-att-invalid-value: Invalid Attribute Value For 'type' In Element 'element'. Recorded Reason: Cvc-datatype-valid.1.2.1: 'xs:' Is Not A Valid Value For 'QName'.

correct your typos in XSD <xs:element name="tolrence" type="xsdecimal" /> (a 'e' and ':' are missing). In XML, you should have tolerence as name of elements. — Loic Mouchard

Errors in your XSD

<xs:element name="dia" type="xs:">

and

<xs:element name="tolrence" type="xsdecimal" />

Then you need a value in the unit and tolrence elements (as they are decimals)

<dia>
    <unit>123</unit>
    <tolrence>123</tolrence>
</dia>

Then use an XML Editor or online XSD validator to check it.
