C# Class iTextSharp.xmp.impl.XmpNode

A node in the internally XMP tree, which can be a schema node, a property node, an array node, an array item, a struct node or a qualifier node (without '?'). Possible improvements: 1. The kind Node of node might be better represented by a class-hierarchy of different nodes. 2. The array type should be an enum 3. isImplicitNode should be removed completely and replaced by return values of fi. 4. hasLanguage, hasType should be automatically maintained by XMPNode @since 21.02.2006

Inheritance: IComparable, ICloneable
