Remarks

You can use processing instructions in XML to indicate that an XML document can be processed by some processor, such as XSLT.

Processing instructions are nodes in the XML tree. When a processing instruction is found in the XML being parsed, LINQ to XML creates an XProcessingInstruction node.
