What does <![CDATA[]]> in XML mean?

Question

I often find this strange CDATA tag in XML files:

Answer 1

It escapes a string that cannot be passed to XML as usual:

Example:

The string contains "&" in it.

You can not:

<FL val="Company Name">Dolce & Gabbana</FL>

Therefore, you must use CDATA:

<FL val="Company Name"> <![CDATA["Dolce & Gabbana"]]> </FL>
