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