What is, and when is used the ![CDATA[ string/variable/constant? (I don't know what is it)

Answer 1

It is a way to escape large sections of text in XML documents.

From wikipedia:

In an XML document or external parsed entity, a CDATA section is a section of element content that is marked for the parser to interpret as only character data, not markup.

By the way, it is <![CDATA[]]>, not ![CDATA[]].
