/**

The TXmlEngTextNode class inherits from TXmlEngCharacterData and represents the

textual content (termed "character data" in XML) of an Element or TXmlEngAttr. 

If there is no markup inside an element's content, the text is contained in a

single TXmlEngTextNode that is the only child of the element. If there is

markup, it is parsed into the information items (elements, comments, etc.) and

the TXmlEngTextNode nodes that form the list of children of the element.

When a document is first made available via the DOM, there is only one

TXmlEngTextNode node for each block of text. Users may create adjacent

TXmlEngTextNode nodes that represent the contents of a given element without

any intervening markup, but should be aware that there is no way to represent

the separations between these nodes in XML or HTML, so they will not (in

general) persist between DOM editing sessions. 

No lexical check is done on the content of a TXmlEngTextNode node and depending

on its position in the document, some characters must be escaped during

serialization using character references.  For example, the characters "<&" if

the textual content is part of an element or an attribute, the character

sequence "]]>" when part of an element, the quotation mark character " or the

apostrophe character ' when part of an attribute.
