    32  * The TXmlEngTextNode interface inherits from TXmlEngCharacterData and represents the textual content 

    33  * (termed "character data" in XML) of an Element or TXmlEngAttr. 

    34  *

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

    36  * of the TXmlEngTextNode interface that is the only child of the element. If there is markup, 

    37  * it is parsed into the information items (elements, comments, etc.) and TXmlEngTextNode nodes that 

    38  * form the list of children of the element.

    39  * 

    40  * When a document is first made available via the DOM, there is only one TXmlEngTextNode node for each 

    41  * block of text. Users may create adjacent TXmlEngTextNode nodes that represent the contents of a given 

    42  * element without any intervening markup, but should be aware that there is no way to 

    43  * represent the separations between these nodes in XML or HTML, so they will not (in general) 

    44  * persist between DOM editing sessions. 

    45  * 

    46  * No lexical check is done on the content of a TXmlEngTextNode node and, depending on its position in 

    47  * the document, some characters must be escaped during serialization using character references; 

    48  * e.g. the characters "<&" if the textual content is part of an element or of an attribute, 

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

    50  * the apostrophe character ' when part of an attribute. 

    51  *
