As default behavior, Tika runs Siegfried to add its detection
to the metadata, but NOT to use detection in determining parsers
etc.  If this is set to <code>true</code>, this detector
will return the first mime detected by Siegfried and that
mime will be used by the AutoDetectParser to select the appropriate
parser.
