The XML Classifier, when called to perform automatic classification by Document Classification Manager, parses the XML document in order to perform the following pseudo steps to determine which XML Property Mapping Script (which contains the actual XSL) to use to perform the automatic classification.
IF DOMDoc contains a Processing Instruction named FileNetDocClass
THEN SET DocType = FileNetDocClass.value
Example: <?FileNetDocClass XMLNewsStory ?>
In this case, the XML Document Type would be XMLNewsStory.
