## NAME
    [XML::DOM::CDATASection] - Escaping XML text blocks in [XML::DOM]

## DESCRIPTION
    [XML::DOM::CDATASection] extends [XML::DOM::CharacterData] which extends
    [XML::DOM::Node].

    CDATA sections are used to escape blocks of text containing characters
    that would otherwise be regarded as markup. The only delimiter that is
    recognized in a CDATA section is the "]]>" string that ends the CDATA
    section. CDATA sections can not be nested. The primary purpose is for
    including material such as XML fragments, without needing to escape all
    the delimiters.

    The DOMString attribute of the Text node holds the text that is
    contained by the CDATA section. Note that this may contain characters
    that need to be escaped outside of CDATA sections and that, depending on
    the character encoding ("charset") chosen for serialization, it may be
    impossible to write out some characters as part of a CDATA section.

    The CDATASection interface inherits the CharacterData interface through
    the Text interface. Adjacent CDATASections nodes are not merged by use
    of the Element.normalize() method.

    NOTE: [XML::DOM::Parser] and [XML::DOM::ValParser] convert all CDATASections
    to regular text by default. To preserve CDATASections, set the parser
    option KeepCDATA to 1.
