When a TemplatesHandler object is used as a ContentHandler for the parsing of transformation instructions, it creates a Templates object, which the caller can get once the SAX events have been completed.
Returns:
The Templates object that was created during the SAX event process, or null if no Templates object has been created.
Set the base ID (URI or system ID) for the Templates object created by this builder. This must be set in order to resolve relative URIs in the stylesheet. This must be called before the startDocument event.
