How attribute is different from a element in XSD?

Element in XSD is nothing but an XML element such as opening tag, content, closing tag, etc. XSD Elements are the building blocks of your XML document. Elements are defined by their occurrence. An element can have sub-elements inside them. XSD elements can be of simpleType, complexType, or anyType.

The attribute in XSD is extra information about the element. The attribute is always a simpleType and has a fixed or default value. An element cannot have multiple attributes of the same name tag.

//example
<test id="5">somevalue</test>

Here, the test is an XSD element and ‘id’ is an attribute of the element.
