application/octet-stream
if the type of the document
can not be detected.
If the document input stream is not available, then the first
argument may be null
. Otherwise the detector may
read bytes from the start of the stream to help in type detection.
The given stream is guaranteed to support the
mark feature
and the detector
is expected to mark
the stream before
reading any bytes from it, and to reset
the stream before returning. The stream must not be closed by the
detector.
The given input metadata is only read, not modified, by the detector.
