TXFANode.XMLInstructionTarget Field
XMLInstructionTarget: AnsiString;
Stores the UTF-8 XML Name of a processing-instruction target; the field defaults to empty and is meaningful only when XMLContentKind is xckProcessingInstruction
The target must be a valid XML 1.0 Name and cannot equal xml in any capitalization; it is separate from the instruction's literal Value data
Use AddProcessingInstruction for validated construction; native serialization validates a target changed directly through this field
