Processing Instructions

As their namesake implies, processing instructions provide explicit instructions to the processing application. These can be identified by distinctive tags comprised of left and right angle brackets coupled with question marks (<?, ?>). These instructions are typically found directly under the XML declaration and can provide any number of directives. For example, the following processing instruction would direct the use of Excel to open the given XML document:

<?mso-application progid="Excel.Sheet"?>
