Question: XML documents are called ________ sections

Answer:

CDATA stands for "Character Data" and refers to a section within an XML document where characters are used as data rather than markup. It is often used to include blocks of text or data that may contain special characters or reserved symbols that could otherwise be misinterpreted as XML markup.

CDATA sections are defined by enclosing the desired content within the `<![CDATA[` and `]]>` delimiters. For example:

```xml
<description>
<![CDATA[
This is a CDATA section.
It can contain special characters like <, >, &, and ".
This content will be treated as character data.
]]>
</description>
```

In the above example, the content within the CDATA section will be treated as literal character data and will not be parsed as XML markup. This allows you to include text or data that would otherwise require escaping or encoding to be properly represented within an XML document.

```xml
<description>
<![CDATA[
This is a CDATA section.
It can contain special characters like <, >, &, and ".
This content will be treated as character data.
]]>
</description>
```
