of type XMPPFile.
value
A String value. You can put here user friendly
description of the file.
Remarks
This property holds description of the file that is sent/received
to remote side. It is optional data specified prior to transfer that
is presented to remote side. Usually users will write here short
description of the file so remote side can decide if it will accept
it or not (since filename by itself doesn't tell them much about the
transfer).
