Remarks
Any declarations are assumed to be in the internal subset unless otherwise indicated by a startEntity event.
The startDTD method is called within the startDocument and endDocument events from the content handler and before the first startElement event.
A document type declaration connects a document to its document type definition (DTD), which defines the rules of the document, such as what tags can go in your document, what tags can contain other tags, and the number and sequence of the tags. This declaration always begins with "<!DOCTYPE", followed by the name of the DTD, followed by a declaration of the DTD or a link to where the DTD can be found. Finally, it ends with a ">" to close the declaration as shown in the following code sample.
<!DOCTYPE NAME [
DTD content goes here.
]>
