* textContent of type DOMString, introduced in DOM Level 3
777
* This attribute returns the text content of this node and its descendants. When it is defined
778
* to be null, setting it has no effect.
780
* When set, any possible children this node may have are removed and replaced by a single Text node
781
* containing the string this attribute is set to.
783
* On getting, no serialization is performed, the returned string does not contain any markup.
784
* No whitespace normalization is performed, the returned string does not contain the element content
785
* whitespaces Fundamental Interfaces.
787
* Similarly, on setting, no parsing is performed either, the input string is taken as pure textual content.
789
* The string returned is made of the text content of this node depending on its type,
793
* ==================== ========================================================================
794
* ELEMENT_NODE concatenation of the textContent attribute value of every child node,
795
* ENTITY_NODE excluding COMMENT_NODE and PROCESSING_INSTRUCTION_NODE nodes.
796
* ENTITY_REFERENCE_NODE This is the empty string if the node has no children.
