public class XMLNSDocumentScannerImpl
The scanner acts as the source for the document information which is communicated to the document handler. This class scans an XML document, checks if document has a DTD, and if DTD is not found the scanner will remove the DTD Validator from the pipeline and perform namespace binding. Note: This scanner should only be used when the namespace processing is on!
This component requires the following features and properties from the component manager that uses it:
