XML

An element is the main XML entity: an opening and closing tag. They need to be properly nested.
```
<name>Vidal</name>
<person/>

<b><i>bad nesting</b></i>
	  
```
Elements can have attributes (id) which have values (123):
```
<name id="123">Vidal</name>
	  
```
The values have to appear between quotes.
