//: DOM Text class.
//- !group=Core/XML!
//- !header=core.h!
//- <p>The Text interface represents the textual content (termed character data
//- in XML) of an Element or Attr. If there is no markup inside an element's content,
//- the text is contained in a single object implementing the Text interface that is
//- the only child of the element. If there is markup, it is parsed into a list of
//- elements and Text nodes that form the list of children of the element.</p>
//- <p>When a document is first made available via the DOM, there is only one Text
//- node for each block of text. Users may create adjacent Text 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. The normalize()
//- method on Element merges any such adjacent Text objects into a single node for each
//- block of text; this is recommended before employing operations that depend on a
//- particular document structure, such as navigation with XPointers.</p>
